* Rewrote MediaRoster.h
* Removed appearantly unused satic variables. Hope this does not break binary compatibility, going to test. * There are three more private methods, which could probably be removed as well. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24558 a95241bf-73f2-0310-859d-f6bbb57e9c96
