Tweak to ffmpeg compatibility layer to support debian's wheezy libav

fix for building with cycles.

simplify WM_MT_context_menu_enum(), use expanded enum property.

remove TRANSFORM_OT_snap_type, use WM_OT_context_menu_enum instead.
add Ctrl+Shift+Tab shortcut for selecting snap type to the UV editor too.

also added icon drawing to WM_OT_context_menu_enum() so it gets the icons from the enum to draw them in the menu.

Add terminate call for crash handler for windows. Also add inactive code
to do backtrace flushing. This code will need DbgHelp.lib which we may
want to only include for debug builds if at all.

Stupid keyboard should know what coders want to type ! (i.e. another typo fix in UI messages :p )

optimization for calcNonProportionalEdgeSlide(), avoid matrix multiply for each vertex.

Grumph, going quicker than the music! :P

transform feature - G-key during transform toggles slide (edge slide or vertex slide), similar to how trackbacll rotate toggles.

add new vertex slide transform operator, different from the existing vertex slide tool based on user feedback.
- no 2-step select edge, then slide. Instead you can slide and select the edge at the same time.
- ability to slide multiple verts at one.

supports proportional option for vertex slide and flipping, both matching edge slide functionality.

Add wave to boost libraries for MinGW if OSL is turned on (still not supported but making sure it works correctly when it is)

Three fixes;

- Previous commit had a line of code of WIP project in it... tss

- Packed Library data was not freed

- Removed recent (post 2.65a) code to exclude packed data from Undo system.
It's internal data thats part of file spec, errors happen for example on
restoring quit.blend or temp saves.

Usability:

Using Proxy Armature on groups: an Undo now doesn't force a complete re-evalution
of this system anymore, so posing works similar as for regular (non linked)
armatures - an undo step goes back to the previous pose.

Before, an undo made the entire armature go to rest pose. Bad bad :)

I need animators to carefully check - report back if there's other issues!
Tested on Gilga character from Tube Open Movie.

Even though we want to get rid of this legacy compo soon, code should compile as long as it is here! :)

code cleanup: rename transform Slide operations to EdgeSlide.

remove 2.57-windows workaround for WM_OT_copy_prev_settings

bge track-to actuator: reverse the order of the cross product rather then negating.

BGE: Fix from HG1 for bug [#32831] "TrackTo aktuator +X direction not working correct" reported by HG1.

Looks like a vector needed to be inverted for the +X calculation.

fix [#33846] Points of Curves in Vector Curves node can't have negative X or Y values/.

BGE: Adding preliminary alpha shadow support for Simple shadow maps. They do not work in the viewport nor do they work for Variance shadow maps.
