• updated the gui to handle new default import tag options objects
• existing default advanced tag options data will be converted to the new system on update
• the petition management panel now presents similar petitions from the same user together, with the relevant data rows in a checkbox list, so janitors can approve/deny many similar petitions all at once

• account modifications now work through JSON
• the account identifier object is converted from yaml to json
• in the path tagging dialog, regexes that do not compile will now say so, reporting their short regex error statement
• fixed a bug that could sometimes occur when cancelling an ongoing gallery query

• repositories will not burn CPU cleaning their updates if there are still pending file/mapping petitions to process
• repositories will clean updates in smaller bursts to reduce the contiguous server_busy time
• fixed drag and drop thumbnail ordering, which actually wasn't working but was accidentally randomly sorted when I tested it!
• a certain kind of error during vacuum that can mean two different things is now caught, and automatic vacuums then suspended while the user figures out what is going on
• revised some v176 update code that wasn't parsing some downloader pages correctly--now, if a downloader page cannot be updated, it will be discarded
• updated to Pillow 3.0.0 on all platforms and fixed some obselete image calls
• general code cleanup
• general code refactoring
