4.6-related wiki pages moved

[Brian J. Tarricone]

Hi all,

The anal perfectionist in me has been annoyed about the 4.6-related wiki 
pages, so I moved them (thanks to a nifty dokuwiki plugin called 
'pagemove').  New pages are here:

http://wiki.xfce.org/releng/4.6/roadmap
http://wiki.xfce.org/releng/4.6/milestones
http://wiki.xfce.org/releng/4.6/known-issues
http://wiki.xfce.org/releng/4.6/installers
http://wiki.xfce.org/releng/4.6/videos
http://wiki.xfce.org/releng/4.6/docs-roadmap
http://wiki.xfce.org/releng/4.6/general-info

Please add further 4.6 release-related pages here.

Also:

Haven't created redirects from the old pages yet, but I'll get to that...
