linuswck 9acff86547 Restructure GUI Code, Improve and Fix Bugs
- Bugs fix:
1. Params Tree user input will not get overwritten
    by incoming report thermostat_data_model.
2. PID Autotune Sampling Period is now set according to Thermostat sampling interval
3. PID Autotune won't get stuck in Fail State
4. Various types disconnection related Bugs
5. Number of Samples stored in the plot cannot be set
6. Limit the max settable output current to be 2000mA

- Improvement:
1. Params Tree settings can be changed with external json
2. Use a Tab system to show a single channel of config instead of two
3. Expose PID Autotune lookback params
4. Icon is changed to Artiq logo

- Restructure:
1. Restructure the code to follow Model-View-Delegate Design Pattern
