New Cache Router release!

I put in a bunch of work on Cache Router today. The brand new 1.0-Beta6 release is out for 5.x and 6.x.

Check it out here: http://drupal.org/project/cacherouter

You should see some noticeable improvement on speed.

Here are the fixes:

Fixed a bunch of bugs and added simpletests.

#273618 by Nick_vh: Fixed checking for gzip in both the content and in the browser request.
#288318 by Jo Wouters: Fix for wildcard replacement.
#313289 by Murz: Fix for wrong check for $map initialization. We should be checking $this->map not $map.
#277078 by Murz: Cache items prefix with APC cache type
#325614 by R. Muilwijk : Fix for updating static cache on set. and Fix for locking problem with all engines.

Stuff I did:

- Cleanup key handling and make sure we are prefixing the static array cache as well.
- Fix serialization to match behaviour of core. This is now fixed in all engines. Thanks to R. Muilwijk for pointing it out.
- Added SimpleTest 2 tests thanks to R. Muilwijk.
- Code style cleanup and some random bug fixes that I noticed.
- Fixed static array caching, now uses $this->key($key) which should offer noticeable performance improvement.

I am hoping we are almost ready for an RC1 release. The only things I want to fix before 1.0 release are:

1) Get SimpleTests to all pass
2) Get Session caching implemented
3) Get some stats action going.
