Hashcat rules handling (native *.rule files) added to JtR

[JimF]

One additional rule was added (to john).  That is eC  (and e?C for a class in john).  hashcat has the E command for title-casing.  The e is an extension of that, where any character (or class of characters in john), can be used as the separator for words.

so JOHN.DOE with e. rule would be John.Doe   Pretty useful since many companies have gone to a firstname.lastname user id scheme.
