Switch nanomap computers over to using get_sensor_levels()

* Added a proc to the map datum which returns what zlevels a nanomap capable computer should display.
* Updated the atmos control, power monitoring, crew monitoring, and camera consoles to use it.
* Changed templates to not show the map button if no map levels are available.
