Move signals to event triggers

Move the generation and initialization of signals to be included in the
available event triggers. The signal trigger consists of subscribing to
a given signal match where when the signal is received and handled, it
causes the event actions to be called.

Tested:
    All current event signals are still registered and received
    Speed changes occur based on temperature sensor change signals
