Description

For conveinence, it would be nice if the RegexField supported inverse matching; i.e. the contents of the field do NOT match the regex when they're valid. I needed this in the course of using a RegexField for username signups. I have a list of undesirable usernames, like so:

INVALID_USERNAME_REGEX = '(admin|root|add|edit|administrator|service)'

Since it's not trival to make a regex that uses against words rather than characters this is useful.
