Makefile.am: Make sure VLC.app will be installed correctly. (Or make sure we won't attempt to install VLC.app).

Fix error in gpg signature verification function. Gcrypt is responsible for freeing the value returned by gcry_md_read, so we shouldn't free it ourselves but use gcry_md_close instead.

Restore resizing functionality with ffmpeg swscale. Please check if crop and padding work as expected and report any regressions.

Contribs : Use Qt 4.3.4snapshot on windows. Compiled with -O3 and patched with the help of Trolltech.

modules/genmf: Use printf instead of echo -n to prevent some weird shell/Makefile issues. (Fix make install on Mac OS X).
