Concerto: increase copies, assign statuses

Concerto: increase copies, assign statuses

Add more call numbers and create multiple copies per branch.
Include BR3 and the Bookmobile for diversity and to provide
some easier testing of search scopes at different depths.

Switch to functions for the purpose of populating call numbers and
copies, so we can make changes in one central place rather than
repeating ourselves like crazy.

For a better facsimile of the real-world, assign Reshelving / Checked
out / Lost statuses to a subset of the copies. (When / if we create
transactional data, we could throw this bogus data away.)
