scon update for new collada libraries

Updated Blender Collada module to newest opencollada API

modified build system for updated opencollada libraries (windows only, other platforms might want to update as well)

I18n: various fixing.

* Reflect changes stated in prev commit about contexts in py code.

* Add a "Plural" context, to handle cases where english does not mark plural at all (e.g. shorten labels of only one adjective). Not so happy with that, but can't see any other way to do it, for now.

* Abuse "ID_CURVE" context for all falloff curves (this should solve some confusion issues, e.g. "sharp"...).

I18n: fix/enhance how predefined contexts are handled in py code. Now they should be specified by an attribute with the same name as the one in bpy.app.translations.contexts named tuple (i18n_contexts.default, .id_windowmanager, etc.).

This way, i18n message extracting code is now able to get the right context!

Fix for node groups, now exposing a socket will copy the default value from internal nodes again. Also this value can be changed in the node group Interface panel.

Fix #34782: Video Editor - Substract after transform fails

Couple of precision issues here:

- Interpolation was rounding trunkcating colors, and because
of some precision issues value 254.999 became 254 leading
to troubles later.

Now color interpolaiton will do rounding to nearest int.

- Subtract was setting channels to something negative which
confused color management (especially negative alpha),

Now subtract effect will clamp channels to 0 from bottom
and also do some tricks to prevent small alpha which
could also confuse color management.

fix [#34636] bpy.app.handlers.load_post not run on startup file loading after splashscreen

Fix #34773: smooth brush used on a shape key messes up the topology

Key block update was missing coordinates for hidden vertices.

BMesh: make the context create operator (Fkay) more logical, before calling each operator check the state that it can even run and do something.

own error in recent commit, uninitialized variable.

fix for loosing recent-files when running 'Copy Previous Settings'.

Fix typo with non-system bullet.

workaround for crash when accessing vertex colors in editmode,
just disallow vertex color access in editmode as is done with UV's.

svn merge ^/trunk/blender -r55594:55635

style cleanup: osl and NULL pointer use, also correct sequencer gap operator id's

Cycles / SunSky:
* Use already calculated theta^2 for theta^3 calculation.

I18n fixes for C panels & menus (we have to specify the default bpyrna context here, else we get the horrible "empty" string (as translation_context of panels is an array, not a pointer, so it's never NULL).

Code cleanup / Cycles:
* Remove unused variable from noise_wave().
