* Consolidation of roomserver APIs * Comment out alias tests for now, they are broken * Wire AS API into roomserver again * Roomserver didn't take asAPI param before so return to that * Prevent roomserver asking AS API for alias info * Rename some files * Remove alias_test, incoherent tests and unwanted appservice integration * Remove FS API inject on syncapi component
