QUI for MPlayer 1.0 Released

At long last, a non-beta 1.0 version is available. This one made it through all of the tests that I could come up with, so I believe it is a stable version. Naturally, this does not conclude my work on QUI, but 1.0 includes all of the features I feel are necessary for a media player, so now I can start on some of the extra things that are nice, but maybe not necessary.

From now on, I intend to start putting my beta releases in a qui4mplayer-devel package instead of the main qui4mplayer one since now there will actually be a stable version and an in-progress version.
