Create Syrup model tables in a 'reserves' schema, just because we can.

Create Syrup model tables in a 'reserves' schema, just because we can.

This is still the 'classic' Syrup database model; we haven't made any
changes here vis-a-vis Robin's model. I've simply used explicit
db_table naming and our custom backend to put the Syrup tables in a
'reserves' schema.

I've also moved the default Django tables (users, groups, etc.) into a
'django' schema. This leaves 'public' empty. Note that I didn't do
this by setting explicit db_table values for the Django tables, but
rather by putting 'django' at the head of the search_path in
settings.py.
