Sample of using build info to generate keystrokes (#412)

* More documentation

* Saving crontab for user  on host

* Restructuring in keeping with recent changes to conventions

* Simplify submitting my fave cbbrowne keystroke by using SEND_STRING()

* Local change, not apropos to have in this repo

* Simplify logic; no need to return so much

* Add in a version key

* Add docs

* Split build date into a separate DEFINE

* Ensure there is a value even if not working within a git repo

* Should not include the compiled code in the repo

* compiled.hex files should not be included in the repo; they represent generated compiled code

* Fix spelling in comment

* Remove more generated files

* Add rule to ignore contents of .build directories; their contents are generated

* Revert removals of compiled files
