MegaST v0.4.12 beta: remembers mounted disks (restored hard disk not seen, fixed in 0.4.14)

Pre-release for testing. Please report what works and what doesn't in the issues (core version, board, TOS, machine settings, disk image).

New: the core remembers your disks (#13)

• The mounted floppy and hard disk images and the TOS and cartridge chosen in the menu are loaded again at the next start, before the ST boots, so a hard disk is found and the right TOS starts.
• This needs the new file atarist/stmount from the zip (1536 bytes) on the SD card. Without it, the core behaves as before.
• Unmounting a drive in the menu forgets it. An image that is no longer on the SD card is skipped.
• A long press of the reset button restarts the core like switching off and on, so the remembered images come back. Unmount them in the menu if you want empty drives.
• Tested in the QNICE emulator, not yet on real hardware: please report whether it works (mount disks, switch off and on, check that they are back).

The menu is unchanged: the 99 byte atarist/stcfg of 0.4.8 to 0.4.11 stays valid. Coming from 0.4.7 or older, copy the new atarist/stcfg (99 bytes) from the zip, otherwise the settings are not saved.

⚠️ Coming from 0.4.10 or older

Hard disk writes were broken up to 0.4.10 and fixed in 0.4.11 (#11). Hard disk images that were written to with 0.4.10 or older may be damaged: restore them from a backup or check them.
