typo in 0.4 prevents adding exclusion regex

[clee]

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.check(self.Validate.REGEX, excludePattern):

but self.Validate.REGEX doesn't exist. It should be self._Validate.REGEX.

I will attach a patch which fixes the typo and prints out any other exceptions which occur in this try/except block

The patch worked for me, but seems to be reversed, so had to apply with patch -R timedrive/settingsdialog.py timedrive-validate_typo.diff
