New GPAC installer for Windows

Some people might be interested in trying out the latest version of the GPAC tools, but don’t have time to compile it from scratch. For those persons, I have generated an installer for Windows from the SVN (revision 2634). It contains the usual things (audio/video support, MPEG-4 Systems stuff (BIFS and LASeR)) but also our latest developments on MPEG-U Widgets and on MPEG-B DASH (Dynamic Adaptive HTTP Streaming).
