CMake: improve finding gstreamer

Browse Source 
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.
