Issue #834198 by Dave Reid, donquixote, mikeytown2: Added static caching to pathauto_cleanstring() for performance.

Issue #876768: Fixed pattern variables not renamed if node type machine name changed. Fixed pattern variables not deleted when node types or vocabularies are deleted.

Issue #931740 by Dave Reid: Fixed Pathauto processing should be skipped if the pathauto_perform_alias attribute is defined for taxonomy terms or user accounts.

Left behind by TGGM script's removal of CVS keywords.

Issue #319070 by Dave Reid, Josh Waihi, DrDeth, JoelKleier, jamespharaoh, tuffnatty: Provide a wrapper for cross-db and cross-field-type concatenation.

#881270 by Dave Reid, greggles | plach: [bookpath], [menupath], [*path] tokens not cleaned: aliases without punctuation removed, lower casing, etc.

#881270 by Dave Reid: Fixed string cleaning not applied to the [bookpath] and [menupath] tokens because they defy the Pathauto token name conventions.

by Dave Reid: Revert API change to pathauto_clean_token_values() since apparently other modules use it??

by Dave Reid: Use the new token-provided invalid context element validation callback and use _form_validate() instead of manually calling _pathauto_validate_pattern_element().
#849582 by Dave Reid: Using _form_validate() directly causes funky errors. We can just use #after_build and it works so much better.

#855606 by Dave Reid | dpearceMN: Check permission to see verbose messages before showing the message about duplicate aliases.

#823648 follow-up by Dave Reid: Allow the location of the i18n-ascii.txt file to be set using the \$conf global.

by Dave Reid: Fixed spelling errors.

#715408 by Dave Reid, sun | greggles, Freso: Use '#wysiwyg' FAPI property and remove _pathauto_warn_wysiwygs().

#608566 by Dave Reid | greggles: Updated changelog by removing it. Bet you didn't see that one coming!

#228762 by Dave Reid, robb, fletchgqc, Bodo Maass | greggles, marcvangend: Fixed un-aliased nodes should still get an alias generated even if the update action is 'Do nothing with existing aliases'.

by Dave Reid: Removed t() from the 'patterndefault' properties in hook_pathauto() implementations. It is not a translatable string.
