This commit adds beta support for running a shell or other program within a micro view. Use the `> term` command. With no arguments, `term` will open your shell in interactive mode. You can also run an arbitrary command with `> term cmd` and the command with be executed and output shown. One issue at the moment is the terminal window will close immediately after the process dies. No mouse events are sent to programs running within micro. Ref #243
