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.

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.
