[MPlayer-DOCS] mplayer plugin

[compn]

a user came in asking about a windows mplayer plugin for firefox
and i found this extension, maybe it should go into the win32 docs for
others to use. i think it may work on any os firefox runs on as well.

the user said it worked for him on apple.com trailers.
