Added a build.properties file for common ant properties
Added a patch to allow linking static ffmpeg libraries
Added ffmpeg-patching and mxe (with pthreads for windows) to build.xml
Removed dedicated build-ffmpeg-* scripts
Removed macosx support (cannot test; should be similar to linux)
Added working linux and windows buildscripts
Updated pom to reflect lack of platform subdirectories
Simplified FfMpeg library loading
Switched stream source to FileInputStream(file.file()) to file.read()

This allows any FileHandle-accessible file to be played as a video,
even if it is inside a Jar. The old method only works for true files.
