suggest: roll threads from fuduntu, dreamlinux into other + close those subs

Although backlinks to threads in some of the relatively inactive subforums may exist, these 2 subs have near zero content.

"Ultra X" and "Rock" subforums fit the same mold
(seemingly not enough activity to merit existence of their distro-specific subforums)

Thanks for the feedback. While there is really no minimum participation level for distributions that are still active, we do archive disto forums when the distribution itself in inactive. I've done so for:

Ultra X
Dreamlinux

Note that all threads and fora are still accessible via direct URL, they will simply no longer appear on the forumhome page
