• added options for disk cache init and maintenance to 'speed and memory' page of options
• abstracted the manage tags dialog into a general purpose 'apply' dialog and a scrollable manage tags panel
• the 'auto-replace entered siblings' checkbox now remembers how it was last set
• uncertain sibling tag counts will now appear like 'tag (1,234-1,456)', showing the range of possible results they represent
• fixed a bug where siblings would be collapsed inside the tag manager object if a specific tag search domain was set
• altering the search text on an autocomplete from 'tag' to '-tag' or vice versa should graphically update more reliably, and an exact-matching predicate will be promoted to the top of the list correctly either way
• calls to upnpc will now kill the process and raise an exception if it hangs for more than thirty seconds
• misc improvements and cleanup
