Radio/model configuration lockout

[jace26]

Hey y'all, I'm interested in being able to have surety over radio configuration for use in a commercial environment where I want standard radio configurations across multiple handsets at different locations. For this purpose, it would be nice to selectively lock some or all configurable items and actions behind a password. This might include locking out the execution of certain lua scripts/tools. I can imagine having to set up the locks in companion as it might make the RC UI too complex and unwieldy. Similarly, it would also be nice to have a configuration hash that would allow operators/inspectors to verify proper configuration of the locked sections.
