small documentation change
ignore default path for bundled gems
Improve how the request path is used to determine redirection when
needed

* pass the request object to the Path from_request method
* include a from_request! method to raise when no page is found
* changed to the ! method as default behavior in current controllers
so there is no API change
Refactor Path#from_request! slightly - think we can accomplish the same thing without the second argument.
Normalize stubs to use Rspec's built-in mock library
Merge pull request #17 from modeset/redirect

Rescue the redirection to give the path a second chance
