Title: Add match option to regexp validator

Add match parameter to regexp options:

type: Boolean default: true

If true (or not set), this validator will pass if the given string matches the given pattern regular expression. However, when this option is set to false, the opposite will occur: validation will pass only if the given string does not match the pattern regular expression.
