doc fixes part 1 (more will come when i find the time to read the rest)

if anything is not ok, please let me know

documentation.html:
* OGG -> OGG/OGM (both file formats are supported)
* somewhat better wording (no real change of meaning)
* update of the current xf86 version from 4.2.0 to 4.2.1
* mga_vid is not old
* partial sync of the options with the manpage (someone with deeper knwoledge
  should check them and finish the sync)
* added 2 links about quoting and correct writing of mails to the mailinglists

formats.html:
* fixing typo interleaved -> non-interleaved (at least i think it's a typo
  please someone check it)
* non-interleaved AVIs should be played with -ni
* OGG -> OGG/OGM
