CMake: improve finding gstreamer
Support checking for multiple versions, first check gstreamer-1.0, then gstreamer-0.10. Add support for finding gstreamer-player. Specify the required components, add the include directories and link with the libraries of the found components. Set the setup variables wxUSE_GSTREAMER and wxUSE_GSTREAMER_PLAYER.
