Pagination fully factored out, and both Activities and Accounts now use
a PaginatedList superclass. Server-side search is done by pressing enter
after typing a search, or by pressing the search button. Works on
accounts, soon will on activities if it doesn't already.
RecordCounter class created from that in activityList, and put in
accountsList. PageCount-type route standardized and made for /users
(/users/count). Created userCache, which regularly generates the
respUser list returned by /users. Added a currently dumb POST /users for
searching/pagination, GET /users is now just for getting -all- users.
go-getted expr, an expression language that seems like it'll be useful
for evaluating local searches. We don't store this data in the badger
DB, so we can't use the nice query form provided by badgerhold.
