Fix whitespace

First pass at a BLE module.  Things that still need to be done, or need some thought:

- Receive data from BLE to the Scout, accessible via Bitlash--ideally via a Bitlash callback function
- Start-advertising, disconnect, and is-connected all available as Bitlash functions
- Put the `StringBuffer bleOutput;` inside the class so memory isn't wasted by being in the global namespace
