Jeremy Penner bf41a54aec Screen stack support
- rename "game-state" to "screen" (like "title screen", "options screen", etc)
- rename :state to :id
- provide helpers to load a screen given a "spec", deserialize a screen back to a spec, manage a screen stack
- rework test repl helper to allow setting the screen directly, instead of tweaking game state
- have start-game take a spec by default

Jeremy Penner cc62dfb054 Gamestate API improvements
- always include the id as an attribute
- implement query operators that return the whole entity, rather than just the ids
- implement update / delete functions which extract the id from the given entity

Jeremy Penner 1e2de1dd99 Implement new input event model.
Input events are now represented as maps containing the complete current state of the user's input devices.
The update method is called with a timeline of all input events since the last call to update.
This neatly solves the "stuck key" problem by making state transitions implicit.
It also solves the problem of different game states (ie. in-game and paused with menu) dealing with input differently.
If part of a game cares about keeping track of all of its input history, and part doesn't, they don't have to fight or know about each other.
