Bread-first bmesh walkers:
- walkers can be run in breadth-first order or depth-first order (previously there was only depth-first)
- walkers keep track of current depth (with this + breadth-first, select nth implementation is now trivial)
- new connected vertex walker (similar to shell walker, but returns vertices instead of edges)
- shell walker can be started from a vertex (in which case the walker starts by queueing all the edges incident on the vertex) or from an edge (walker starts by queueing the single edge)
- bug fix for walker reset (was emptying states, but not clearing the visithash)
- bug fix for select nth (indexing for deselection was walking through *all* connected elmeents, to match trunk it should only walk through *selected* connected elements)

Fix dissolve crashes.

For some cases, this will make dissolve work as expected. For other cases dissolve will fail gracefully (it will report unable to dissolve, but not crash). To get dissolve to work in these cases we need to define what happens when you dissolve a disk that has faces which share more than one edge.

undo of 40542 (meant to make two separate changes)

Fix dissolve crashes.

For some cases, this will make dissolve work. For others dissolve will still fail (report unable to dissolve, not crash) in some cases. To get dissolve to work in these cases we need to define what happens when you dissolve a disk that has faces which share more than one edge.

Merging trunk into soc-2011-tomato up to revision 40540

Commented and tagged some unused vars (gcc warnings...).

Fix some MSVC 2010 warnings (including one apparent bug in intern/elbeem/intern/solver_relax.h)

whitespace cleanup

Committing patch #27442: Adaptive time step for fluid particles. The number of
subframes can now be altered automatically while an SPH (fluid particle)
simulation is running.

Minor: Other UI strings typos and tweaks. Also updated french po & mo.

Changed the behaviour of the Perlin 1D geometry modifier. Now it distorts
strokes using the curvilinear abscissa of stroke vertices as the input of
the Perlin noise generator (instead, the Perlin 2D geometry modifier generates
noise using the 2D coordinates of stroke vertices in the image space as the
input of the noise generator).

patch [#28616] Multiple particle systems support
from Andrea Rugliancich (andrearu01)

BGE Animations: Fixing various Action Actuator compatibility issues reported by Dalai in issue #28723.

added bone envelope to the editbone UI, also use more BLI_math functions for armature drawing.

correction to armature drawing code, was implicitly casting the bone flag to a short when it contains flags in the int range.
also was converting pose bone constflag to an int which is harmless but may as well not to it.

fix [#28459] Fly mode problem: "Precision enable" not working in 2.59

also added back freelook (from 2.4x) - so you can loop about without changing direction.

give a more useful error when building with an old ffmpeg.

make new rna variables more consistant with existing names.

manual update on changelog (python API)
Change as suggested by Campbell.
I'm not sure if this is the way to do for enums, I will check with him later

Python API changelog r37840-40524 (HEAD)
updating the doc.

I'm also including the latest API dump with it. This helps to keep track of the revisions to update and the next person updating doesnt need to build an old Blender for that (as I just had to).

I updated the sphinx_changelog_gen.py with this info as well.
I'll update changelog.rst manually next. I'm not so sure how to indicate that the properties were replaced instead of only removed.
