Fixed: Issue where regular expression was returning false positive on profanities ending in 2 letters of the same e.g. ass would see as as a profanity.

Updated regular expression to be lazy so it checks as many characters as possible.
Refactored Check class to make it easier to follow flow.
Renamed config file from badwords.php to profanities.php.
Added spec methods to test `ass`, `as` strings.
