Add bucket CRUD and read-only Projects/Labels to Settings page

New "Maintenance Buckets" section: create a bucket, add a pool item by
title (creates the task and assigns it in one step), remove an item,
delete a bucket (unbuckets its tasks rather than deleting them).

New read-only Projects and Labels sections (name + color swatch) --
both are simple enough that read-only is the right call on web, per
user direction, rather than duplicating the Android popup's editing
UX.
