VSConfig.cmd: check that we support the given CMake generator. ReadMe.txt: typo fix.
BuildDeps.cmd: fix bug in cd'ing to the assimp dir. Use /p:platform="%VS_PLATFORM% explicitly for defining the platform for MSBuild calls for all non-CMake projects.
Export SystemInfo functions.
Custom (including x64 config) VS2008 solution and project files for protobuf. It would appear that the sln fails to build on command-line, but builds just fine when using the IDE. This would seem apply also for vorbis and maybe some other deps too (Ogre deps at least, IIRC). Also do not download VLC binaries if making a 64-bit build.
Exclude VlcPlugin from the 64-bit Tundra build.
ReadMe.txt: replace CMake generator that is not yet supported with a generator that actually is.
BuildDeps.cmd: instruction additions and tweaks.
BuildDeps.cmd: do try to generate QtScript bindings for QXmlPatterns as it's excluded in our Qt build.
Protobuf project files: use the same output directory on both 32-bit and 64-bit builds.
AssetBundles: Add Store and Provider ptrs to IAssetBundle. Add SubAssetCount() to the interface, implemented now in zip bundle.
AssetsWindow: Implemente proper parenting for asset and bundle items. Parent sub assets to its bundle item. Fix asset and bundle item paths to trim away the storage base url from the shown ref. Simplify search filter placeholder text logic.
Some size_t conversion warning fixes.
Couple more size_t conversion warning fixes.
