Pre-release.

Added:
1) Added check for transition to new speed and parity.
2) Added the ability to stop scanning before polling all addresses.
3) A window has been added that allows you to set the value of multiple registers at once. Supports both simple saving on the device and the saved-sent mode.
4) Added check for parity and speed changes.
5) Added output of current voltage to the table.
6) Now, when you click on an indicator in the table, the corresponding element will be highlighted.

Minor updates:
1) Now the device settings take into account the number of boards found during scanning.
2) When you close the main window, the device turns off.
