Reorganization of the wiki

[maddiin]

I started to reorganize the front page of the wiki: 
http://wiki.apache.org/couchdb/FrontPageNew

I think the current front page is hard to read because of the CamelCase 
links and is cluttered with too much information. I would like to group 
pages and get rid of CamelCase links/headings.

This would also affect already created pages (for example change the 
link from "GettingStartedWithFuton" to "Getting started with Futon").

Therefore the old links would be outdated, but it should be possible to 
redirect to new locations with "#REDIRECT pagename" within wiki pages, 
at least the moinmoin documentation says so.

So please have a look at the proposed front page and let me know what 
you think. If no one is strictly against it I´ll go ahead and take care 
of the changes and your suggestions.
