Background now set by CSS, added doctype and charset.
Closed all tags properly and removed bogus <P> tags around block elements. Manpage is really spelled man page and punctuation marks should not be separated by a space from the word they follow. git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@6428 b3059339-0415-0410-9bf9-f77b7e298cf2
