projectmoon bf4ce24b79 Better public API for user variables, avoid allocations in Context.
The database API for user variables has changed somewhat again, this
time closer to the proper vision. There are now two separate sled
Trees in the Variables struct, one for user-defined variables, and one
for counts. Keys have been changed to be username-first, then room ID.
The signatures of the functions now also use a strongly-typed struct,
UserAndRoom.

As part of this, the Context object now once again avoids allocating
new strings.

Other random changes included here:
 - Remove tempfile crate in favor of sled temporary db config.
 - Add bincode crate in anticipation of future (de)serializing.

projectmoon a53ce85f38 Add db migration support, change variables schema.
This is a bit of a large commit that adds basic database migration
support. It also alters the way user variables are stored in a way
requiring manual migration of existing data. The first automated
migration adds variable count in a new place.

projectmoon 6cdc465a2e Add database and storage of user variables.
This commit introduces the Sled embedded key-value store for keeping
track of user variables on a per-room basis. Extensive changes were
made to the command module to separate concerns and also pass the
database "connection" down the line.

 - A new "Context" object was created to hold information and state
   needed for command execution (namely the database).
 - Database is very simple for now, storing only user variables.
   Refactoring later for storing more complicated types.
 - State actor moved into Actors struct, in preparation for either
   more actors, or ripping the whole thing out entirely.
 - Other modules are also more properly separated, notably
   the config module is entirely self-contained.
