Integrate and test request routing

[fake51]

See RequestRouting

This is working on test, needs to be tested and moved to alpha and production

Note: to test this, you need to check if we have broken links. Basically, the routing will work as normal for anything BUT groups app. Only groups app currently uses proper request routing.

So, to test:

• check if there are broken links outside the groups app. The interesting ones are for rox apps (don't bother bout the old /bw/ code)
• for the groups app, check if there are broken links, things that send you somewhere you didn't expect

nothing broken so far... maybe some one else should test, too

I haven't found any broken links, too.
