Proper routing implementation

[aleksanderakero]

Need to be able to route url's to specific controllers and actions.

Added a new branch for this now. This should have working router functionality. Though we should might consider doing other refactoring work at the same time as this.

Also put a switch for this functionality in config. $conf['routing']['enabled'] = true/false. Triggers another processRequest function in index.php in site.

Sidenote: Seems a bit weird to be setting this in site. Maybe we should at the same time add a bootstrap file or something that does these kinds of things..? at least move it from site to core somewhere.
