FS#25 - Change sf::PostFx to a more general purpose pixel shader class (sf::Shader)

Browse source 
Updated the PostFx sample, renamed to Shader
Renamed all the static X::CanUseX() functions to X::IsAvailable() to make the API more consistent
Moved .def files from /build/VC200X to /src in CSFML
Minors fixes in CSFML
