Adding first rudimentary version of tagging and filtering. New users get three tags: morning, afternoon and evening. At the moment, one can not change these tags or add new ones. There are also some problems: tagging a newly added task, also tags one of the existing tasks. Also, when having an active filter and removing the corresponding tag from a task, that task is immediately hidden, although you are still editing it.

rename user._tagFilters to user.filters
for now don't live-bind to {#each _user.tags}. There's a derby bug
here, so we'll have to refresh when users add new tags until we get
that fixed
add new tag
add tag-editing context (add new, delete). still have to refresh after everything, do to the live-bound each bug
