Add the binlog

[Fayti1703]

TODOs:

• Declare structures
• Add Turn Log
• Add Action Log
• Add Combat Log
• Add stringifiers/renderers
  • StandardBinlogRenderer FullStringBinlogRenderer (similar to the in-game format, but fixed bugs)
    • This also renders to a string rather than a string[].
  • CompatBinlogRenderer TraditionalBinlogRenderer (precisely the in-game format)
• Show binlog in Accessor Deferred: BinaryMatrixEngineAccessor is incomplete #2
• Run a couple tests Deferred: There are no tests #4

Fixes #5

[Fayti1703]

Generally pretty happy with the engine implementation of the binlog so far -- PlayerID handling might need some optimization (we know the player's index at the top level!) -- but other than that, this went quite smoothly.

[Fayti1703]

The core Engine implementation, plus the two renderers, is done now; still missing any sort of testing on this.

[Fayti1703]

Merging this now and deferring test running into #4, and Accessor binlog rendering into #2.
