Revert part of commit 29079, cleanup of particle path drawing logic

This commit and other commits attempting to fix it broke various things. The
main thing that changed was that instead of computing children/paths in
advance as part of particle_system_update, this was moved to do it just before
drawing or rendering. I've changed back that behavior and tried to keep the
other fixes in the commit.

When the new particle system was just committed, it also worked this way but
gave various problems, and I had to remove that behavior to get things working
stable. Basically it meant that you could get have a path cache that was
outdated in various situations, and it doesn't fit well with dependency graph
evaluation order.

This fixes:
#22823: Children Particle Rendering is broken
#22733: Particle objects not displayed
#22888: SigSegV when rending hair particles
#22820: Another SigSegV when undo adding hairs in particel edit mode
Some particle setups in dupligroups.

The three bugs that the original commit fixed are now also still working in
my tests:
#21316: Hair weight drawing is wrong
#21923: Consistent Crash When Rendering Particle Scene.
#21950: Path rendering option for particles causes crash

[#22876] Add new scene, stacker ".00" bug
finding duplicates is a bit faster now too since it doesnt split the name and number before comparing ID's prefix.

2.5: installation paths, local directories (in the same folder as executable)
are now considered system rather than user directories, as you would expect
these to override any system directory for local installations.

Audaspace Py API: Getting rid of string literal warnings.

bugfix [#22890] Setting the Maya keymap gives python errors

Autoplay: Fullscreen now really works.

Merging revision 30434 from my GSoC branch, log: Fixed sound wave display bug for sounds that are not full length.

Fixed sound wave display bug for sounds that are not full length.

* Applied patch from nicholasbishop that refactors calculation of the grab delta into a function with less duplication

PNG Compression can now be set, writing uncompressed PNG's is significantly faster for high resolution images - 2k.

48Hr Bugfix: Paste pose not correctly updating

Removed some antiquated cruft that used to work around the old anim-system.

Added rudimentary SpaceNav event capture code for Windows.

Disabled RawInput mouse code.

Logic Editor: fix for float values steps and precision (reported by Mal Duffin (malCanDo) over email)
The UI wasn't working.
+ renaming motion blur rna to motion_blur_factor
+ fixing "using wrong dna" for min_y constraint actuator RNA

simplify thumbnail reading and remove some warnings

sequencer outline, credits on a black background wasnt easy to see.

fix for assigning any ID in rna, it would not run id_lib_extern() which means the library reference would be lost on reload.

BGE Py API:
* Sphinx autorun file.
* bge modules are now autogenerated
* added aud module

Merged changes in the trunk up to revision 30416.
