Putting sabre/http into an external package. WIP
Moving to sabre/http WIP
Auth is mostly working again.
Deleting contents of temporary directory
Fixing post vars.
Fixed remaining unittest problems.
Missing send()
Moved URLUtil to the sabre/http package.
A new approach to method handling.

Every method handler now gets a reference to the request and response,
making it easier to do sub-requests.

Standard method handlers are moving to a core plugin.

It's now possible to listen for specific methods, such as
beforeMethod:PATCH.

New event: 'method' for a standard method handler.
New event: 'afterMethod' for post-processing

Server is now responsible for calling $response->send();
All built-in http methods are now handled by the CorePlugin
Migrated the ACL plugin as well
Fixed sig.
docblock mistakes
CardDAV passes the tests.
Tests are passing.
Merge pull request #345 from fruux/external-http
