* Some UI rework
* Start removing (retry) logic from ruffyscripter to ComboPlugin
* Cleanups all over
* Remove TDD stuff, this can be done independently of a pump
* New SPI/API methods confirmAlert, readReservoirLevelAndLastBolus
* Add warning and error codes from Combo manual
* Rework commands to just execute an action (verification will be in
ComboPlugin eventually, together with retry logic)
