Localize error enums to modules, better DB error reportng.

Implement Actix for state, refactor bot code. Instead of using an Arc Mutex for state management embedded directly into the bot, utilize actor pattern, with the idea that this will be much more useful than simply logging a message once in the future. This also refactors the bot code so that instead of a single run_bot function, the DiceBot struct now has a run() method attached to it. This also necessitated changes and cleanup to the dicebot main, which is for the better anyhow. The error and config types are also now in their own files, and implemented for more in-depth use cases.

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.

Encapsulate config with Arc. Further bot code cleanup. Only expose config settings via methods on the Config struct. This allows default value handling to live entirely inside the config code, solves various borrowing issues with the "create default bot config value" solution, and allows us to avoid cloning the bot config values. The downside is that the config must now be in an Arc since its ownership is shared in multiple places and the matrix SDK requires thread-safe types (perhaps in the future we re-compose traits and use Rc for config instead). This commit also further cleans up and splits up the bot code for the matrix connection, notably making the main message event handler smaller by splitting out the "should we process the message" checks into a separate function.

UrlParseError(#[from] url::ParseError),
Upgrade to Matrix SDK latest (Store Rewrite) and Tokio 1.0 This upgrade introduces a handful of breaking changes in the Rust Matrix SDK. - Some types have disappeared and changed name. - Some functions are no longer async. - Room display name now has a Result type instead of just returning the value. - Client state store has breaking changes (not really a big deal). This required introduction of a new type to store room information that we are interested in on the context struct. This new RoomContext is required mostly due to unit tests, because it is no longer possible to instantiate the Room type in the Matrix SDK.

IoError(#[from] std::io::Error),
Dice pool and command parser rewrite to prepare for user variables. This commit refactors the parsing and rolling for the dice pool system to prepare for support of user variables. The nom parser was dropped in favor of the easier-to-understand combine parser in most parts of the code. A breaking change was introduced into the dice pool syntax to allow for proper expressions and variables. The syntax is now "modifiers:pool-amount", e.g. "n:gnosis+8". The simple single-number syntax with no modifiers is also still understood. Dice pool expressions are translated into a Vec of "Amount" objects, stored by the DicePool struct. They have an operator (+ or -) and either a number or variable name. When the dice pool is rolled, this list of Amonuts are is collapsed into a single number that is rolled, as it was before the refactor. The following changes were made to the dice rolling code: - Store Vec<Amount> on DicePool instead of single number to roll. - New struct RolledDicePool to store result of a dice pool roll. - Remove Display trait from DicePool, move it over to RolledDicePool. - Separate extra dice pool info into DicePoolModifiers. - DicePoolModifiers is shared between DicePool and RolledDicePool. - Dice parsing and rolling now return standard Result objects. This commit does NOT enable support of actually using variables. Any dice pool roll containing a variable will result in an eror. The command parser was also rewritten to use combine and rely on the standard Result pattern.
