Tab autocomplete

[Jaredk3nt]

To properly match the user-experience of a terminal HomeTerm should provide tab autocomplete. Set up a listener on tabs that will fill input based on current string.

For the first run we don't need to support tabbing through options just displaying multiple options if available and completing if only a single option is available.
