SQLite analytics recording

[mildmojo]

This change adds stats recording to a local SQLite database.

Status

This is the version currently installed on the Lexitron for the Louisville Arcade Expo, Lexington Comic and Toy Convention, and the Danville Arts Center gallery installation.

I haven't merged this into master yet because it currently blows up if you don't have the SQLite binary in your PATH or alongside the moonshot binary. Looking for a solution there.

Data Recorded

DB Event Name	Description
boot	Launcher process began
moonshot_start	ROM Check screen completed
game_start	Game launched with LEX button
game_end	Game process exited
game_error	Error launching game (nonzero exit statuses not yet detected)
attract_start	Launcher became idle, rotating through game cards
attract_end	Player touched the controls, disabling attract mode
coin	Coin inserted with no game active

Implementation

The stats module uses SQLite via the command-line executable because I couldn't find a good native JS library for Windows. They either needed to compile a binary against SQLite libs (using MSVC++ or somesuch) or operated entirely in memory, requiring periodic dumps to disk (yuck). The command-line sqlite3 executable needs to be available on the system PATH or copied to the same directory as the moonshot executable.

DB Schema

Table name: stats

Column	Type	Description
id	Integer	Autonumber primary key
event_at	DATETIME	Event timestamp
event	TEXT	Event name as listed in table above
game	TEXT	Game slug if applicable (e.g. 'compromised')
notes	TEXT	Other annotations (e.g. error message for game_error or elapsed time for game_end)

Notes

This updates the Moonshot version number from 0.1.0 to 1.0.0 because swagger.

This also updates the project for NW.js, which is based on node v0.11-0.12. The project now uses some child_process APIs that are specific to v0.11+. Sorry to combine all the font changes in here; they're needed for the new NW.js.

This doesn't include any UI or tools for getting data back out of the DB. That would be a good first secret code, no? 💃
