typo in 0.4 prevents adding exclusion regex
In version 0.4, attempting to add a regular expression to the "exclude" list in the setting dialog returns the error message invalid regular expression in a pop up. Looking at the code, there is an unqualitfied try:/except: block which hides a typo:
if not self._Validate.
but self.Validate.REGEX doesn't exist. It should be self._Validate.
I will attach a patch which fixes the typo and prints out any other exceptions which occur in this try/except block
