Fixed gcc-fat.sh failing to build Objective-C sources correctly. This would fail if the compiler was given a .m file _and_ no "-o" option; it would fail to automatically calculate the correct .o filename in this situation. Thanks to Ethan Lee for the help tracking this one down!

WinRT: fixed multi-touch bug whereby 2nd, 3rd, etc. fingers weren't moving Only the first-pressed finger wpuld get reported as having moved (via SDL's touch APIs). Subsequently pressed fingers wouldn't report as being moved, even though the OS was reporting (to SDL) that they had moved.

Added missing brackets in test source assert messages.

Fixed two typos in test source.

WinRT: removed '-' from build script file names Most of the other build scripts don't include a '-' in their file names. This change makes the WinRT build scripts use the same convention.

WinRT: added scripts to build Release copies of SDL for all WinRT variants These variants include: - Windows 8.0 for x86 - Windows 8.0 for x64 - Windows 8.0 for ARM - Windows 8.1 for x86 - Windows 8.1 for x64 - Windows 8.1 for ARM - Windows Phone 8.0 for x86 (for use with the Windows Phone emulator) - Windows Phone 8.0 for ARM - Windows Phone 8.1 for x86 (for use with the Windows Phone emulator) - Windows Phone 8.1 for ARM

WinRT: updated docs to include details of recently-expanded GLES2 support

WinRT: fixed crash when trying, and failing, to load the opengles2 renderer The crash would occur when a WinRT app explicitly tried to create an SDL_Renderer using the "opengles2" renderer (via SDL_HINT_RENDER_DRIVER), but OpenGL ES 2 / ANGLE .dlls weren't packaged in the app.

WinRT: enabled OpenGL ES 2 support on Windows Phone The "future-dev" branch of MSOpenTech's ANGLE/WinRT repository (at https://github.com/msopentech/angle) includes support for Windows Phone 8.1. This change allows it to be used in conjunction with SDL's OpenGL functions.

WinRT: updated an OpenGL-related code-comment
