Fixed issue #456: Unified cache driver

This is the beginning of work on the unification of all
calls and appeals to the driver cache.

+ Updated: Now ACL, Filter and Route will use Cache::instance
  as way to call current default cache driver. Removed in these
  classes Kohana::cache and used simply Cache::instance()->get()->set().
  In future it will be replaced by one object Gleez::$cache
+ Fixed: Cleanup & added PHPDoc
+ Fixed: Minor cleanup spaces & code
