DirectX 11 Overlay

mumble_ol.dll increased in size, from 127 to 291 KB
new dependencies: MSVCR, D3DCompiler (DLLs)
because dx11 does not include the effects anymore, the DX SDK sample effects has to be used and adapted, for compilation. By default it compiles as a static library, but thus will use libcmt, which will result in a fatal error, duplicate definition of functions. To fix this, the effects lib has to be compiled with the linker settings “ignore specific default library: LIBCMT”, and “additional dependencies: MSVCRT.lib” (added D for the debug versions).
