bugfix [#20510] .blog file causes crash (again rev25592)

bugfix [#20528] Crash when applying scale to a Bezier curve

freeing particle modifier would access freed memory (only to tak the psys to be deleted), set to NULL after freeing and check before tagging.

- disallow the change the layer operator in localview.
- toggle setting the layers (mainly useful when accessed from the keys)

[#20455] Spotlight halo with deep buffers: render crashes

fix for [#20499] Smoot view doesn't work for all view keys.

bugfix [#20534] Blender crashes throghout compositing

bugfix [#20542] Crash 2.50a0 Click event in Console window Report mode

- WM_OT_context_cycle_int wasnt working (also wasnt used anywhere)
- remove console zoom operator, use WM_OT_context_cycle_int instead.
- use WM_OT_context_cycle_int for text editor zoom also (Ctrl +/- and Ctrl+MouseWheel)

dont draw object centers when drawing the depth buffer, grease pencil would get its depth messed up by object centers when with 'Surface' mode.
Also fix own error with drawing grease pencil depths, wasnt setting v3d->zbuf back to its original value.

grease pencil retopo improvement: join lines when endpoints match are close and are co-linear within some error limits.
still very slow, needs some speedups.

grease pencil depth option 'Stroke Endpoints' works well when painting onto mesh surfaces as well as other grease pencil lines. change ui to show this.

patch from Cessen
Adds a new set of bones to rig types which are to be used for weight paint vgroups, in some these have some more segments to account for twist. also use Aligoriths new copy transform constraint.

new python submodule. eg.
from bpy.app import binary_path, version, version_string, home

can add constant variables from blender here as needed (maybe functions too... bpy.app.memory_usage() ?)

editbone.transform(matrix) function, requested by Cessen.
Also added matrix.median_scale attribute to get the average scale from the matrix, use for scaling bone envalopes.

fix for mistake in last commit. also forgot to call RNA_parameter_list_end() in some places, (ok the function does nothing now, but some day it might do)

sphinx support for documenting multiple return values

PyRna float/bool/int slicing.
- fixed slice assignment.
- fix for slowdown where getting a slice would get the entire array and free it for every item in the array (malloc and free for arrays >32).
- fix for thick wrapped returning an array referencing the original pointer when coercing into a mathutils type failed.

TODO
- slice assignment currently only sypports lists.
- dimensions are ignored for multidimensional arrays.

RNA Ray casting function for python access, uses BVH acceleration structure (same as shrink wrap), very fast & useful for object placing scripts.

Python Example.
hit_location, hit_normal, face_index = object.ray_cast(ray_start, ray_end)

- first rna func to use multiple return values
- currently casts in object space, may want to cast in worldspace too.

support for multiple return values from rna functions & support for returning arrays, (no functions are using this yet).
patch from Elia Sarti, (vekoon) with some modifications mainly for the python api.

- multiple values are returned as a typle in the order that are defined.
- added support for registered types returning multiple arguments (untested).
- renamed func->ret --> func->c_ret, since this only defines what the C function returns.
