Removed the use of $this in the closure, restricted variable name derrr :)
Merge branch '3.2/master' of https://github.com/enov/krestful into 3.1/master
resolve_accept $strict parameter is now an array

$strict was a boolean and controlled 3 Accept- headers:
  - Accept
  - Accept-Charset
  - Accept-Language

Now each can be configured separately
$_accept_strict is now an array + 3 functions to get

the resolved accept accept-language and accept-charset
added Kohana_Controller_REST from Kohana 3.1
