Create UI menu for selecting top-level commands

[gamebits]

When team51 is run without any parameters, it outputs a list of support commands before dropping back to the command line. The user can then run team51 again with the desired command.

When no command is passed, a nicer UX might be to present the user with a selectable menu — similar to Newspack's Knife tool:
