Subject: feat($http): add support for aborting via timeout promises

If the timeout argument is a promise, abort the request when it is resolved.
Implemented by adding support to $httpBackend service and $httpBackend mock
service.

This api can also be used to explicitly abort requests while keeping the
communication between the deffered and promise unidirectional.

Closes #1159
