Integrated Testing Options and Email testing

For the CI-Bonfire project, I adapted this library to work with their password requirements by:

* Passing the options object to the Strength class during initialization. These options pass three settings to force numbers, symbols or mixed case
* Adding two additional tests that run if two of the force options are checked
* Added email validation for sites where the users login is their email address (I.E Facebook, Twitter, Linked in, etc).

I had thoughts of adding a Twitter Bootstrap compatible callback to the JQuery class, but made a custom callback for Bonfire instead.
