Added a test to check how quotes around SOAP action are handled
Added test for HTTP 404
Match incoming URLs against compiled expressions instead of direct paths and SOAP actions
Made URLData's internals aware of match targets (RESTful channels)
Refactored out returning headers on 200 OK to a separate method
Accept url_data in __init__
Fixed failing tests
Added tests for zato.server.connection.http_soap.url_data
Won't fight with rebase - code for RESTful channels so far
