Bump maps flip: now white means salience, black means concavity

Files created in blender before this revision should be rendered in
exactly the same way they used to render before.

Patch by Morten Mikkelsen, finished by Ton and me.

i18n: fixed mistage in message generator which lead to some messages disappeared.

Also, cleaned up po files from unused messages.

add bevel weight to editmode buttons, patch from Psy-Fi or IRC.

Minor: Other UI strings typos and tweaks.

fix for crash generating messages.txt, I wasn't getting this crash because I had 'WITH_PYTHON_SAFETY' enabled which was using different iterators (which dont crash), now there on by default.

made headless and no-python configurations work again and added --factory-startup to doc building command.

po : adding note for windows translators/devs + remove backup function in update_po.py
(no more tons of *.po~ in the folder)

More normal fixes, this time for object mode calculation of vertex normals

Fixes for a few bugs in selection and the interaction between BM_SELECT and BM_HIDDEN:
- Select all was selecting hidden elements
- Select flush was also selecting hidden elements (so selecting two *visible* vertices of a *hidden* edge selected that hidden edge)
- Several places were using BM_SetHFlag(elem, BM_SELECT) directly, when they should be using BM_Select(bm, elem)
- In certain scenarios, "reveal all" could leave you with selections which aren't valid in that selection mode (e.g. lonely edges selected in face select mode)

Recast: upgrade library.

- Upgrade Recast library to latest portable version
- Implement recast_qsort based on FreeBSD qsort.c to have
portable thread safe quick sort for use in conversion routine.
- Better default value for the Build Navigation Mesh operator

Cycles:
* Remove duplicate declarations.

SVN maintenance.

remove the pot and messages file, they change too much with only minor changes to the source and can be regenerated.

improvements to translation message generator

- for rna stringsinclude the path as comment, eg:
#~ bpy.types.VertexGroup.name

- skip strings like %dx%d or -X.

- for strings extracted from python scripts include file:line reference as with C files.

- have messages in order they appear in the file, files and classes sorted so it reads more logically.

- extract these comments from the messages.txt file into the pot file.

OSX: another non-ASCII char, sorry

Minor: Other UI strings typos and tweaks.

Commented and tagged some unused vars, added some var init (gcc warnings...).
Wonâ??t go further, most other warnings are from GE or intern/extern lib code...

Minor: Other UI strings typos and tweaks. Also updated french po & mo.
(grrr... That update created tons of new things... back to ~40% done...)

Fix #28416: setting fluid simulation start time to anything other than zero
gave wrong results. Note how in this code it already incremented to the start
time and then incorrectly added it again. Patch by Chris Foster, thanks!

Fix #28769 & #28768: problem with duplicated keymap items after fix yesterday.

fix for error generating docs, write all files as utf-8
