Choko Multi OS system images

These new images will append "_SD" to the partition names when running from SD card (or "_MM" if running from eMMC) to avoid conflict if same image is used both in eMMC and SD card.

• Lakka v4.3
• Lakka v5.0

NOTES:

• First time booting into Lakka it will rename partitions and expand the LAKKA_DISK partition, then reboot.
• When it finally boots into RetroArch, go to Settings -> Input -> Menu Toggle Gamepad Combo and select how you want to call the menu when playing a game (to exit, for example). "Select + Start" is the same way as the official CHA firmware works.

Known issues:

• When rebooting the CHA, sometimes it will stay off. This seems to happen more when we write something into the boot partition. In any case, just press the power button twice with a few seconds in between (one will "really power off", the second time will boot again) or unplug power cable and plug again.
