[WIP] RESTful routing syntax for UrlManager

issue #303
Here is the proposal for RESTful routing syntax:
https://gist.github.com/cebe/5674918
doc enhancements for #461
improved UrlManager RESTful syntax regex
unit test for UrlManager RESTful routing syntax

removed test param 'appClass' as it does not make sense to configure
application class for all tests, some explicitly need webapp where
some might explicitly need console app.
Merge pull request #461 from cebe/rest-urlmanager

[READY] RESTful routing syntax for UrlManager
