*
* === Changelog ===
* Version 2.1 (18/05/2008)
* Added a jQuery method to add a new rule: jQuery('input[@type=password]').pstrength.addRule(name, method, score, active)
* Added a jQuery method to change a rule score: jQuery('input[@type=password]').pstrength.changeScore('one_number', 50);
* Added a jQuery method to change a rules active state: jQuery('input[@type=password]').pstrength.ruleActive('one_number', false);
* Hide the 'password to short' span if the password is more than the min chars
*
* Version 2.0 (17/05/2008)
* Completly re-wrote the plugin from scratch. Plugin now features lamda functions for validation and

* Added default messages object for i18n
* Changed password length score to Math.pow (thanks to Keith Mashinter for this suggestion)
* Version 1.2 (03/09/2007)
* Added more options for colors and common words
* Added common words checked to see if words like 'password' or 'qwerty' are being entered
