projectmoon 042ecc40e0 Properly format dice plurality in CofD dice pools.
Fixes #30.

projectmoon 1b0003ff1b 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.

projectmoon 66f9bc6013 Move original dice rolling code into its own 'basic' module.
This gives it parity with the other systems: cofd and cthulhu. More
refactoring and a rewrite later as we trend towards more
system-specific implementations.

projectmoon 39e6eb9b46 Implement support for user variables in CoC dice rolling.
Also comes with reorganization of the dice rolling code to centralize
the variable -> dice amount logic, and changes the way the results of
those rolls are displayed.

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.

Needed for further development of different systems that rely on these
kind of expressions, and lays groundwork for future changes.

projectmoon 7e44faf693 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.
