* Added tablet pressure support (size/strength) for weight paint and vertex paint
* Added tablet eraser support for weight paint and vertex paint (inverts the effect of the current tool)
* Removed the old 'soft' option, now weight paint and vertex paint use the influence curve
* Made the default brush use a smooth influence curve, rather than sharp
* "RNA Path" and "Array Index" for the active F-Curve in the Graph Editor are now shown in the properties region. These are greyed out unless the F-Curve cannot be evaluated, in which case they can be edited to make the F-Curve work again
* Made the Push and Relax operators in Pose Mode fit on a single row in the toolbar, since they're opposites of each other.
Included more tools, such as Edge Slide and Shrink/Fatten in toolbar to make them easier to find.
Did some reorganization of tools in the mesh editing toolbar to categorize tools better.
Made some tools like Grease Pencil tools more compact in the UI
Contributors list isnt used much in our C code so probably its easier if people just use svn blame for this.
Can change if this isnt acceptable but I guessed people didnt care so much since most scripts had no header.
* Extrude and Duplicate for Armatures now use proper macros instead of manually calling transform themselves. This means that repeating these operators now works properly.
** NOTE: there's a bug with macros now which prevents the 'forked' extrude operator working correctly. Bug report filed for this.
* Included the proper operators for extrude and duplicate in the toolbar + menus. The operators used there did not activate transform, which meant that users often could not tell that the operation had occurred at all.
* Restored the Grease Pencil tools to the toolbar
Probably, if the reason they were commented out before was so that the repeat stuff is visible, we can swap the order of those two. Otherwise, it's good to have somewhere for the operators now (so that the hotkeys can be found)
* Hotkey displays in the tooltips now show the keymodifier too
For example, "D LeftMouse" or "Ctrl D LeftMouse" for the Grease Pencil operators, instead of just "LeftMouse" or "Ctrl LeftMouse".
Added an option for normalize_all that keeps the active group at its existing weight while normaling all other groups around it.
Thsi makes it easy to paint up to 100% where all other groups will use progressivly less until the active group is 100% and all others are 0.
Added weight operators to the toolbar
* Fix AAO showing Distance property even though it is not supported.
* Fix texture buttons not displaying texture stack from the node material.
* Small visual tweak to particle mode options.
