* Emitter
New exposed controls allow you to manually fire a single beam, and get
signals whenever it is toggled on/off/fired.
It doesn't allow a player to toggle it on/off (must be done physically).
ID locking the emitter will also lock out the ability to fire the
emitter via USB.

* Temperature Pump
This works exactly the same as the other USB controlled pumps, with the
addition of setting the heat rate.

* Temperature Control Unit
The USB interface now allows this to be remotely turned off and on like
the other USB pump interfaces.
## Why It's Good For The Game
These three parts are crucial to engineering/atmos projects, and gives
experienced players more depth to toy with circuits.
