Extend Mission Interface with display on UI

[maxwey]

The mission interface needs to be able to display a message box or other GUI element to take user input and interact with the user (such as if an alert needs to be created)
Adding this to the mission interface will allow for easier user implementation of subclasses.

• Add setup message box code to allow for it to be set and to be used
• Implement ISRMission setup message box
• Add logic in the orchestrator to allow for it to summon message boxes
• Add ability for Mission to communicate with the rest of the UI (e.g. add message to the console)
