Christopher Snowhill 731e52c440 Build libOpenMPT from source once again 
Bundle libOpenMPT as a dynamic framework, which should be safe once
again, now that there is only one version to bundle. Also, now it is
using the versions of libvorbisfile and libmpg123 that are bundled with
the player, instead of compiling minimp3 and stbvorbis.
