Release v1.2

The loader internal struct offsets changed a bit, updated internal_defs.h to compensate (it's stupid we have to do it this way). Now it will probably only work on firmware version 80.1 or higher (or equivalent).

Basically: The flipper CLI will only run when no other applications are running (i.e. the loader's internal flag is not set). Unfortunately, in order to access the CLI through this app, the app needs to be running. When the app starts up, it does some hacky memory things to reset this flag and convince the loader that no applications are running, allowing the CLI to start up without throwing the annoying "Other application is running, close it first" message. This should now work properly on the newest firmware to reset the flag, which was broken by the change from 79.1 to 80.1.
