mplayer should be moved to universe

[Cesare Tirabassi]

Dear all,

bug 214727 
(https://bugs.edge.launchpad.net/ubuntu/%2Bsource/mplayer/%2Bbug/214727) has 
been raised on the subject.
mplayer is a direct rdepend for many packages, and indirect for I guess many 
others.
Your help on this would be appreciated, please check if there are missing 
packages that should be part of the change, or mark invalid those which 
should not be part of it (either because of license or dependencies reasons).

Many thanks for your help,

Cesare
