This PR allows selection of csrfTokenPattern to be used. Support for HMAC based token pattern and encryption based token pattern added. Defaults to double submit cookie pattern.

Closes #121

Thanks @dougwilson for helping out in opening up PR creation for non-existing collaborators like me, who would love to contribute in this repository.

Team, please let me know your reviews. I have added new test cases too. Old ones need not be changed as the change is backward compatible.

While going through the OWASP documentation, I realized that we can have the csrfTokenPattern as an input for a pattern factory that helps select and execute the generation of the token and its validation. Also the factory design will help in pluggable implementation of more patterns in future.
