Title: Store and show recently-used categories list

* Adds Category data class, "categories" table & content provider
* When search filter is empty, show last 25 used categories
* Once we have used categories, hide the skip message.

It's also possible to do a prefix search on the local database of
recently used categories, but I haven't included it in this commit
as I'm not satisfied with the resulting UI.
