SDL: Update game controller database on launch (#177)

Expands upon existing custom SDL mappings functionality: b82e789d4f

Downloads an updated game controller database (gamecontrollerdb.txt) on launch, which only updates when a new file is available. This keeps the database updated between SDL releases.
