3D Audio GSoC:
Implemented basic audio animation.

* AnimatableProperty: Propper cache writing and spline interpolation for reading (the solution for stair steps in audio animation)
* Animatable properties so far are: volume, pitch, panning
* Users note: Changing the pitch of a sound results in wrong seeking, due to the resulting playback length difference.
* Users note: Panning only works for mono sources, values are in the range [-2..2], this basically controls the angle of the sound, 0 is front, -1 left, 1 right and 2 and -2 are back. Typical stereo panning only supports [-1..1].
* Disabled animation of audio related ffmpeg output parameters.
* Scene Audio Panel: 3D Listener settings also for Renderer, new Volume property (animatable!), Update/Bake buttons for animation problems, moved sampling rate and channel count here

speed button mapping to ndof sensitivity change operator.

update make install rule for scons to support i18n

fix [#28096] Custom gradient for weightpainting in mask mode not working properly.

New option for multires modifier: Subdivide UVs

Enabled by default and also enabled for older filesm so
there should be no regressions.

In some cases it's useful to not use subdivided uvs for multires.

Camera tracking integration
===========================

- Small code cleanup.
- Added missed notifier for animation play start.
- Fixed bundle colorcode detection (it didn't use track
offset to determine distance between original track
position and bundle projection).
- Changed behavior of alt-g grabbing. Now it defines offset.

Merging r38733 through r38779 from trunk into soc-2011-tomato

fix [#28095] Select Pattern don't select all the bone in edit mode
& some style changes.

fix error in writing dupligroups for X3D export, may have effected other exporters too.

report an error when user blender versions other then 2.4x for animation playback.

sequencer add strips now check for overlap by default (option can be disabled for python when this can become problematic for automation).

automatically update the redirect from http://www.blender.org/documentation/250PythonDoc/ when uploading docs

only initialize snap from the scene settings for view3d and image spaces since snap in the 3D view was enabling snap in the graph editor and sequencer without a button to disable it in those spaces.

minor cleanup of rna
- use an rna enum-set for proximity vert/edge/face options.
- rename some flags.
- better conform to rna naming conventions.

Don't write library_materials tag when there are no materials.

refix for #27912: crash after mesh.materials.pop() (fixed wrongly on rev. 38299 - patch by Benoit Boilsee

bug spotted while reviewing a patch.
things are working now

Material Diffuse Color animation COLLADA import.

Merging r38740 through r38764 from trunk into vgroup_modifiers.

vgroup_modifiers: coded a way to test whether the dm needs to be copied (i.e. if the affected cdata layer is or not the original one).
However, as this piece of code tends to slow down things (see e.g. scene 5 of WeightVG test blend file), I deactivated it for now...
