Huge commit: VERSE

- All code is in #ifdef ... #endif
 - Only make build system is supported and you have to add:
    export WITH_VERSE=true
   to user-def.mk file
 - Blender can share only mesh objects and bitmaps now
 - More informations can be found at wiki:
    http://mediawiki.blender.org/index.php/BlenderDev/VerseIntegrationToBlender
    http://mediawiki.blender.org/index.php/BlenderDev/VerseIntegrationToBlenderUserDoc

  I hope, that I didn't forget at anything
