* Action Editor - IPO curve names are shown properly again. Added anim_ipo_utils.c (old editipo_lib.c) file back. This will need to be removed when I port IPO system to RNA.
* Keyframing code - uncommented more of the code that's now working
* Made the 'preview range' button on timeline header draw more clearly
* Restored y-position translations needed for gla-stuff, as gla stuff sets viewport + matrices!
* Fixed alpha-problems with icons. The ft-font drawing was turning off GL_BLEND when it was done, which screwed up the icon drawing (previous names were drawn with 'standard' fonts only)
* Removed Context arg from drawing funcs. Passing anim-context instead.
* Properly initialised new theme settings ported over from animsys2.
Initial commit of drawing code for Action Editor / Dopesheet. By default, the Dopesheet is now enabled (like in AnimSys2). There are still a few unresolved problems (like bad alpha blending for icons, and keyframes still not being drawn). However, these will be resolved in due course.
Moved time_ops.c contents to anim_ops.c, as the operators there are applicable to all other Animation Editors too. anim_ops.c will therefore contain all operators which will apply to all Animation Editors (i.e. change frame, frames/seconds display toggle, and soon Preview Range tools).
As such, added new global 'Animation' keymap like for View2D and Markers, which will ensure that these tools can be accessed in an uniform way across editors.
Note that the order that these things are added is important, as the Animation ones will often 'steal' events from the View2D and Markers ones if placed before the others. To prevent that, we'd need to be able to set boundboxes here...
Brought back the Filtering API for Animation Editors. This is the 'backbone' of the current Action/Dopesheet Editor code, so it is essential to have this working.
* Fixed current frame number drawing in Animation Editors, so that the little frame number indicator box gets shown (animsys2 feature).
* Made all Animation Editors draw markers and preview range
* Added new 'Animation' submodule under Editors. This will be used to house all code + features that are used by many different Animation Editors (Action/Dopesheet and IPO) as well as other parts of Blender.
* Added back some of the core code need by the Action/Dopesheet editor, which will also be used by IPO Editor.
* Brought back file for keyframing management code (i.e. keyframing.c), but there's still quite a lot of missing stuff that I'll need to restore, so in the meantime, it's #if 0'd out.
* Moved markers code to this new module (I'm not sure whether SVN will recognise this change, as TortoiseSVN doesn't seem to have any obvious copy/move commands)
