Generalize logic for vert/edge/face selection:
- index cycling.
- selection bias with mixed modes.
Details:
- Edges now support index cycling (as verts/faces did already)
- Cycling over near elements is now only enabled when the mouse position remains the same.
- No longer do 2 selection passes to perform index cycling.
Fixes:
- Edges behind the view could be selected (surprising nobody reported!)
- Selection bias now only changes the element that gets picked without interning the return distance
(was buggy with mixed modes).
In addition to the unlink icon to clear a value,
When cleared, show an eyedropper to select objects or object-data
(was already available via the EKey).
When mixing vert/edge/face with select-visible,
face selection could fail when not close enough to the center.
This also fixes a bug where the bias for verts over edges would
prefer faces over edges too, making edges harder to pick.
Mixing edge with other selection modes works more predictably now.
- distance from edge check wasn't clamping 0-1
- vertex bias wasn't taking pixelsize into account.
- index & pass counter were floats
Also some improvements
- use BMesh lookup tables when available.
- use structs to avoid issues getting out of sync.
copy.
What happens is that the strip is copied, but it still refers to the old
scene. Here we need to fix this by referring to the copy of the strip
and also do it after copying to make it order independent.
Following the initial action management commits for 2.74, blurrymind pointed out a
problematic workflow involving the "Browse Action" dropdown in the Action Editor
which would lead to actions being accidentally lost. Namely, it turns out that
game animators frequently flip between different actions from the Browse menu while
working.
While the new up/down operators and/or other NLA based tools are better suited to this
without the problems of actions getting lost, some additional precautions were needed
for the Browse menu as well. So now, if the active action will have no users as a result
of the switch (i.e. it was a new action, and the user is checking on a previous action
via the Browse menu), this action will now get stashed. This workflow is not perfect though,
as there is the problem of the stashed action strips not reflecting the actions they reference.
When a NLA strip is being tweaked, it should not be possible to use the Action Editor to change
the action that it uses. Instead of changing the action in tweakmode, it now exits tweakmode
first before doing so.
As reported by zeffi, the "show_points" option was not working in master.
It probably broke recently, after some changes meant that the point sizes
weren't geting set prior to drawing these points anymore. Since this was
originally added as a debugging tool (though it is now somewhat redundant
due to the stroke editing functionality, which uses/exposes the same points),
this option wasn't really that important. I have decided to add back a toggle
for this to the UI though, since it can be used for some interesting effects...
A new function (RunPythonCallBackList) to call all python functions
contained in a python list was developed.
This function has:
- first argument is the python list of callbacks
- second argument is a python list of arguments
- third argument is the minimum quantity of arguments
- forth argument is the maximum quantity of arguments
It improves flexibility and supports *args.

Rename calc_flatten_center to calc_area_center,
since theres no 'flatten' spesific logic there.
Also refactor calc_area_center, calc_area_normal, calc_area_normal_and_center
so they're next to eachother - they're almost the same,
having them scattered about isn't helpful.
A Python API for the collision group / mask has been added:
```
KX_GameObject.collisionGroup
KX_GameObject.collisionMask
```
The maximum number of collision groups and masked has been increased from eight to sixteen.
This means that the max value of collisionGroup/Mask is (2 ** 16) - 1
EndObject will now activate objects that were sleeping and colliding with the removed object.
This means that, unlike now, if a rigid body starts sleeping on top of another object, when the latter is removed the rigid body will activate and fall, rather than float midair as before.
Collision groups that do not intersect used to collide on the first frame. Now this has been fixed so that they collide appropriately.

Flush edits only when saving global undo. This will stop freeing of PBVH
in sculpt mode, which introduces some pretty severe freezes, especially
in dyntopo. For global undo we flush the contents of the global undo
buffer which does not include localized edits of sculpt/edit mode, so
those data will not get saved anyway.
New Check option "Show Shadow Box" in shadow panel of sun lamp to get
feedback about which objects project shadows.
