Development wiki spring (autumn) cleanup

Hi,

at the conference, I heard multiple times that the wiki is a mess beyond
saving. Not a friend of defeatism, I took a look: The wiki currently has 2700
content pages, and the OOo wiki had >10.000 pages, when people said the same
there and I still got it cleaned up decently mostly single-handed(*).

As developers, we have actually have decent wiki pages but we should lead by
example for other teams. We currently have ~100 development wiki pages with
more than 1000 views each. If we focus on this should be able to keep that
reasonably clean without too much effort.

You find them sorted by views and linked for your convenience here:

 https://wiki.documentfoundation.org/User:Bjoern-michaelsen/DevPagesCleanup-2013-10

What we should do is:
1/ DELETE pages that contain misleading content unless they can easily be fixed(**)
2/ Link as much as possible between pages to make them more discoverable
3/ Tag categories and the development menu on those ~everywhere
4/ If you wrote a awesome wikipage not on this list (less than 1000 views),
   think about the "why": its likely going back to points 2 and 3
5/ As a last resort mark stuff as "obsolete and kept for historic
   sentimentality" in red letters, but see point 1.

I hope that by leading by example we (developers) can motivate others to clean
up their part of the wiki too.

Best,

Bjoern

(*) with some 3000 edits, but yeah its possible.

     esp. the "I rather have it rewritten by someone with current data" point
