Summary:
========
The idea here is to move the texface options into the material panel.

1 - Some of the legacy problems 2.49 and 2.5x has with the texface system:
==========================================================================
1.1) Shadow, Bilboard and Halo are mutual exclusive (in the code), yet you can
select a face to be more than one mode.
1.2) Sort only works for blend Alpha yet it's an option regardless of the
Transparency Blend you pick.
1.3) Shared doesn't affect anything in BGE.
1.4) ObColor only works for Text objects (old bitmap texts) when using Texture
Face Materials. (not address yet, I so far ignored obcolor)
2 - Notes:
============
2.1) Now "Use Face Textures" in material Option panel will work in Multitexture
even if there is no texture channel.
2.2) In FaceTexture mode it will use TexFace all the time, even if you don't
check the "Use Texture Face" option in the UI. It's a matter of decision, since
the code for either way is there. I decided by the solution that makes the
creation of a material fast - in this mode the user doesn't need to mess with
textures or this "Use Texture Face" option at all. I'm not strong in my opinion
here. But I think if we don't have this then what is the point of the Texture
Face mode?
2.3) I kept references for tface only when we need the image, UV or the tiling
setting. It should help later when/if we split the Image and UV layers from the
tface struct (Campbell and Brecht proposal).
3 - Changes in a Nutshell:
==========================
3.1) "Texture Face" panel (in the Mesh/Object Data panel) no longer exists. Those settings are all part of the material properties, visible when Game Render is set.
3.2) "Texture Face" Shading mode (in the Render panel) is now called “Single Texture”, it needs a material for special settings (e.g. Billboard, Alpha Sort, …).
3.3) New options in the Material Panel
* Shadeless option in the Material panel is now supported for all three Shading modes.
* Physics is now toggleable, this is the old Collision option.
* Two Side (on) is now called Back Culling (off).
* Alpha Sort is one of the Alpha options, together (and mutually exclusive) to Alpha Blend, Alpha Clip, Add and Opaque (i.e. solid).
* Shadow, Billboard and Halo are grouped in the “Face Orientation” property.
* "Face Textures" and "Face Textures Alpha" (under Options) can be used for all but GLSL shading mode (to be supported in GLSL eventually).
* The backend in the game engine is still the same as before. The only changes are in the interface and in the way you need to think your materials. The bottomline is: It’s no longer possible to share materials between faces that do not share the same game properties.
4 - Acknowledgment:
==================
Mike Pan for the design discussions, and testing along the whole development process.
Vitor Balbio for the first hands-on code with the interface changes. That helped me a lot to push me into work on that.
Benoit Bolsee and Brecht van Lommel for patch review (* no one reviewed the whole patch, or the latest iteractions, so I still hold liability for any problems).
Blender artists that gave feedback and helped testing the patch.

--it's still really simplistic (and slow!) so don't try fixing an entire mesh! xD
Also, don't use it on a mesh with a mirror modifier yet, just noticed that it does both vertices instead of one.
Minor UI text update for Vertex Masking
Normalize, Normalize All, Invert, Clean, and Levels.
Face mask and vertex select/mask are now mutually exclusive options.
Went ahead and allowed vertex selection support and masking for vertex paint.
'A' key could override pose mode's select all (like face mask)
Minor note, changed the icon to the vertex selection icon, but it still doesn't force face mask to turn off.
Clipping is still not functional in wp.
And I'll need to hear how the backbuffer select is supposed to work for lasso select since the selection is arbitrary.
Weight Paint Vertex Select tweaked to act like edit mode's select and Circle select was added, but clipping is not working properly for either.
Select all was added too, but to the Q key until I look into overriding A's select all bones.
The select vertices checkbox was moved to the header, but it does not force face select mask to turn off yet--and it doesn't have the correct icon.
There will definitely be an update tomorrow to fix the problems with all or most of the issues.

From the patch description:
ValterVB on #blendercoders submitted a long list of missing tooltips in Blender, and I went through the list and added all I knew. After that I crowdsourced the rest by putting a spreadsheet on Google docs and having people fill in the missing ones that I didn't know. So if there's some weird tooltip in there that doesn't make sense, that's why.
Thanks to Wolter, spacetug and others on BlenderArtists for contributing tooltips.
1. Removed pinning, at least until after trunk
reintegration (it's a usefull feature, but
incomplete).
2. Ripped out the subclassing code I originally
wrote so bmesh would be more usable for modifiers
(I ended up improving CDDM instead).
3. Inlined some of the macros in bmesh.h, still need to
do the macros in bmesh_operator_api.h.
4. Removed the BMESH_ITER_*** macros (except for BMESH_ITER_INDEX).
They were too clunkly to be worth it.
Discussed with Campbell, it's not actually bug and it's more about limitation
of topology mirror. It will work properly when both sides of mesh have matching
unique topology.
Added note to tooltip, so now unpredictable behaviour shouldn't confuse users
so much.
Also gray out "Topology mirror" when "X Mirror" is disabled.
