Blender Git Loki

Added changes for escaping from rendering by pressing the ESC key.
ESC key press checks are performed 1) before entering Freestyle, and
2) after the completion of the view map creation.

revert joes commit and apply change from Aligorith.
remove scripts dir only.

ideasman/brecht: please don't touch this again. this clears the .blender folder along with everything else; oddly enough it left in the .B25.blend, but bookmarks/recent file lists were nuked. anyway, I just made the install folder deletion off by default. if you must do it, do it on the build systems you yourselves use/maintain, don't touch scons.

Merged changes in the trunk up to revision 26856.

fixing cuckoo bugs
- no i really don't like abusing group indexes (would like to have written indices .. but spell checker complains SIGH )
anyhow
lattices and curves do not care for ambiguous vertex group index any more
just take weights as they are set

Further consolidation of the view map creation.

Made Controller::_EPSILON constant with the value 1e-6. Previously,
the _EPSILON value was computed based on the minimum edge size within
the scene being rendered (in some cases, the computed value resulted
in zero). This does not seem to make sense, because _EPSILON has been
used as a tolerance threshold of floating-point arithmetic errors
throughout the view map creation. Since Blender uses single-precision
real values for mesh data representations, the new constant _EPSILON
value looks more adequate.

Smart Extrude (hotkeys are tentative)

Ekey: Extrude Region
Based on selection totals:
Extrude region along normal if at least one face selected
Extrude vertex along normal if only one vertex selected (experimental)
Extrude edge on its plane if only one edge selected (experimental)
Extrude with no constraint axis otherwise

Shift-Ekey: Extrude Individual
Based on selection modes and selection totals
Individual Faces if face select and some faces are selected
Individual Edges if edge select and some edges are selected
Individual Vertice otherwise

Alt-Ekey: Extrude Menu (only shows valid options for selection mode and selection totals)

Mesh selection totals in RNA (patch by Campbell)

Remove debug print

strip quotes from Buildinfo for bpy.app.build_*

Calling operators from Python with non-default context was broken (need to assign to the right variable).

Python deprcated PyCObject, use PyCapsule instead.

Merge -c 26848 from COLLADA branch into trunk.
