Imbuf types refactor.

ImBuf types were getting stored as bitflags in a 32bit integer which had
already run out of space. Solved the problem by separating file type to
an ftype enum, and file specific options to foptions.

Reviewed by Campbell, thanks a lot!

Use regex for cmake config parsing

Fix T45397: Frameserver rendering no longer works in 2.75 or 2.75a

Issue was caused by a typo in original multiview commit.

Fix T45385: Crash on render occurring when two hair modifiers are active that both use a UV mapped material for render

Not sure it's totally correct solution, but seems reasonable because it's
possible dmcache is set to ISCHILD.

Someone more familiar with the particles code might want to revisit this :)

Minor tweaking to Knife header text.

Confirm/cancel shall always be first, and also makes more sense to have
define cut/close cut/new cut together.

Shortcut-to-string converter: add 'dbl-' in front of key when expecting a double-click.

I think this is the only Keymap value we really need to handle here...

Add new modalkeymap usage in helper header message to Knife tool.

Add new modalkeymap usage in helper header message to Fly mode.

Cleanup: style

Remove redundant string copy

Missed essential part in previous commit.

Or how to epic fail a fix when working on two different systems.
Or how to increase your commit rate.

Fix T45375: Cant clear temp fluid cache after closing Blender (Windows).

There was two different issues here actually:
* Own (very high) stupidity only gave 8 chars to file name (sic).
* list dir returns dirpaths without a trailing slahs, but expects them to have it it seems. :|

Cycles: Expose "Max Bounces" for the world light.

When using MIS, the world is treated as regular light and in this case
we can now also limit the maximum amount of bounces, the background light
will contribute to the scene.

This can improve performance in some cases, where it's e.g. sufficient to
only have a contribution on first 1-2 bounces.
Examples can be found in the differential.

BGE Clean-up: New EXP prefix for the BGE Expression module

The expression module now uses an EXP prefix and it follows a
distribution similar to blender.

Additionally the hash function in EXP_HashedPtr.h was simplified and the
files EXP_C-Api.h &.EXP_C-Api.cpp were deleted because were unused.

Fix crash in redraw timer

Was modifying wrong regions flag, that could also be NULL.

Add ability for redraw timer to run for fixed time

Also avoid accessing context vars in timer loop.

PyAPI: Use separate writes for operator reports

This allows us to temp override the stdout and extract individual reports

Docs; Py API gotcha's section

Minor corrections and cleanup

Use const for direntry strings

File Browser: Fix possible bug and some minor tweaks

BLI_add_slash appended to a char *, a potential buffer overflow

Also partially removed an assert, which failed after changing file format of a saved image. We need a better way to handle such cases.
