Lemon Emu Release v0.2.3

• Added a "Continue playing" card on the games list, and playtime/last-played/sessions sorting on the Statistics screen.
• Lemon Cheater: freeze/unfreeze a found value so it stays fixed (infinite HP/ammo/etc.), with a dedicated "Frozen" view to manage them.
• New input macro recorder/player for the on-screen controller - record a sequence of button presses and replay it, optionally looped.
• Auto-updater now points at this repository (previously misconfigured after the fork) and checks for new releases on launch.
