Easy to forget deactivating Sandbox mode #6

AdamsLair: "Make it really obvious that Sandbox mode is active. Something the user can't miss."

i added a signal [button]
- displays green when all ok
- displays red when user should be aware that the current editor state has a risk
- i added a yellow signal image but have not used it
