- boring code cleanup:
- cleaned and unified a bunch of the new taglist sibling and parents display logic and other legacy variables. it now basically all derives from one storage/display state, so behaviour across the program should be more unified. this may cause confusion in some more advanced dialogs, so let me know anywhere it looks weird
- the 'favourites' autocomplete tab in 'edit/write' a/c dropdowns now show siblings and parents for the current display service
- the tag suggestions favourites dropdowns and taglists in the options now show siblings/parents according to the current service
- the 'url class precedence' routine, which tests more 'specific' url classes first when trying to match an url, has a subtle logic change--now, url classes are first considered more 'specific' according to number of path components and parameters that have no default. this stops an url class with multiple optional parameters overriding another with a single fixed parameter (this is what affected the tumblr downloader above). the specific (descending) sort key is now (required components, total components, required parameters, total parameters, len normalised example url)
- refactored client object serialisation access routines to a new db module
- refactored database transaction code and status tracking to a separate object
- refactored some more tag definition routines to the master tag module

next week

I am having trouble fitting in the network improvements. This coming week is supposed to be a 'medium size' job week, where I would usually push hard on something heavy, but I'll save it for the network stuff. I'll look at my big network improvements job, triage what is reasonable to do, and try to just grind some proper work out.
