* 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)
* Rework commands to update state in field as command progresses
rather than returnin/throwing.
* Initial version reading bolus and error history (no DB sync yet).
Base basal rate, TBR, last bolus are redundant, they're already displayed on the overview
and the treatment tab. When they're not in sync, that's an error of the ComboPlugin.
* Add info about last command ran to the Combo tab
* Don't refresh data more than once a minute.
* Specify not only error, but also command that raised the error in
alert notification
* Make command execution (RuffyScripter/ComoboPlugin.runCommand) more robust (I still suck at threading).
* Return all possible states in PumpState
* Add absolute TBR to PumpState
* Add NoOpCommand to fetch state data from pump
* Display returned pump state in Combo fragment/tab.
