Part V - Converting OpenTX 2.1 Scripts

This section also covers some of the requirements for scripts that are necessary for them to function properly under both OpenTX 2.2.

New features

LUA Widgets (Horus only)
LUA Themes (Horus only)

Changes

Lua Themes and Widgets run in a separate Lua environment. They are isolated from the other Lua environment which runs other scripts. This means they can not share variables, etc... (Horus only)
Function scripts can have a background() function defined (similar to the Telemetry scripts). It will be called periodically when the switch that activates it is FALSE.
Horus doesn't support Telemetry scripts.
Telemetry and Mix scripts maximum file name length (without extension) was reduced from 8 to 6 characters.
Telemetry and Mix scripts maximum number of inputs reduced from 8 to 6
