v1.0:
- Displays support
- define TYPE F/G and rearrange ports
- multi-DS18b20 support on lane
- skip non-important DS18B20 during init
- rewrite Main Cycle to unification: some sensors can be absent, ex: T_hot_out can be absent because i'ts used as target
- 2 on-board buttons support: +/- aim
- DISPLAY: indication: real and aim
- RS485_HUMAN: remote commands +,-,G,0x20/?/Enter
- buttons: < > increase_decrease t
- simpliest thermostat scheme: only T target
- rename all procs
- RS485_PYTHON: print to console inspite of mode diring init proc
- faster wattage overload processing
- write aim value to EE if needed, period: 15 mins (eq. 1041 days)
- deferred stop of hot side circle
- 80 microseconds at 9600
