Config panels reorganization (new "Source" panel added). Sensors directly on mainPanel.
WheelSpeed/trainerLoad might be hidden ("no speed" profile and check to set visibility)
Removed duplicate code from handlers (power targeted don't provide wheelSpeed). "Speed from power" is to select instead.
Autoload/autorecover on start, autosave on quit.
Configurable sensors: database, creating sensors, building configFields, non-translatable names.
Handling removal/additions not done yet. Config editor as well.
