Fix(app::command_interface): Add a (workaround) print function

The default print function prints to stdout, which obviously
doesn't work with a tui application. This wrapper however is a
rather poor workaround, as it only works with strings (lua `print`
calls `tostring` to turn non string values in something printable).
