Fix for paths commit from Andrea:

For Mac, there was no code supporting Carbon. Added a stubs function
to make it compile, but it doesn't work yet properly.

Fix cmake/OSX build after path changes.

remove unused var warnings in linux

This patch implements the proposal outlined here:
http://wiki.blender.org/index.php/Dev:2.5/Source/Installation/Proposal

Original patch by Matt Ebb.
Contributions by Nathan Letwory, Damien Plisson and Andrea Weikert

NOTE:
This is a work in progress commit, some work still needs to be done on the SCons and CMake files for this to work properly, but at least should compile and the files should be created in the right directory.

Commit discussed on IRC with Ton and Campbell.

Fix #22028: rendering from 3d view was OR-ing with scene render layers,
this isn't helpful, so just use 3d view layers.

Fix #21894: backface selection wasn't working correct with < 24 bits colors,
e.g. thousands of colors on OS X, due to use of uninitialized value. Problem
tracked down and patch provided by Shane Ambler, thanks!

Fix for 15-day-old bug causing crashes when loading old 2.49 files, especially those with animation.

Reverting 29563 ("* Moved do_versions_ipos_to_animato from blender.c to readfile.c, where it should be.") part to the original version that (so far) is guaranteed to work fine.

While this means that "nice software design" isn't obeyed once again, this works and the other approach doesn't. So far there really isn't anything really obviously different between the approaches, even after trying a few different placements of the version patches within the file-reading internals.

commenting group timeoffset since it causes groups objects to recalculate modifiers etc. constantly even when animation isnt playing.

last fix still could give corrupt sound, rather then updating the sound info just add and remove the sound handle.

swap strip data wasnt updating sounds

convenience functionality for browse button (requested by Colin for the sequence editor, useful for managing files for the final edit)
- Holding Alt while clocking on the browse button opens a file browser with the containing dir.
- Holding Shift opens the file its self in the default application.

obscure but at least theres a tooltip so its not totally hidden.

Fix for [#22714] Constraints stack : move up and move down buttons problem
* Constraint template now uses 2 rows as well, when the area width is small.
* UI Code could use some code/layout cleanup still, will look into that soon.

'Copy To Selected' (right click menu item) now works for sequence strips, useful for copying blend modes & opacity

sequencer
- effects strips now add directly above the strips they operate on (almost always what you want)
- blend mode for new image/movie/scene/color strips is now cross: without this adjusting alpha will fade to black rather then the strip below.
- SEQ_HAS_PATH macro didnt include sound-ram or sound-hd
- meta drawing code has misleading variable names (from own commit).

- draw sequence strips within metastrips using their real start/end and channel positions.
- dont show color balance unless its enabled.

sequencer re-assign inputs back

== Sequencer ==

This fixes:
[#22722] Removing a sequence strip doesnt remove assosiated fcurves

by using the same hack that is used for moving curve-data along with the
strips on grab.

Should be cleaned up (both functions!) by making sequencer-strips
finally true IDs.

Until that happens, there is only an more or less ugly way of doing
that.

home key to center the camera offset.

disable ref-counting for groups. groups work differently where they are only removed on load if they include no objects.
this was causing groups to be removed by rna if a group's field was cleared and the file was saved (even when it was used elsewhere).

better reporting for file i/o failier, use system error message in more places: Permission Denied, No space left, File not found etc.
- blend load/save uses os message.
- image load gives os message. (remove check for slash at end of line, just let the os report an error)
- python api load image/font/text raise errors with message (was just retuning None for image and font)
- minor edits to py api errors.
