This release adds the `add`, `remove`, and `replace` commands which make it much easier to program a Tock board with multiple apps.
Other features:
- Sort apps by binary size for the MPU.
- Auto find .bin files so you can just run `tockloader add` in an app directory.
- Check to see if Make has thing to build and warn the user.
- Allow arguments in a more flexible order.
- Better ignore bluetooth devices on mac when searching for a board's serial port.
