Added a set of atmospheric analysis sensors to the integrated electronics module
Consists of 7 new input parts. Pressure, temperature, o2 n2 co2 and phoron levels. The last part is a general atmospheric analyser which has all 6 of those functions in one unit. The multi-purpose part uses triple the complexity and power so it is only worthwhile if you need more than 2 of the output pins.
Please note: There are no changes to the icons, all parts use an existing icon - the one from the advanced medical sensor. I did not feel that this was important to change but someone will probably want to at some point.
Fixes every issue in #3683. Every single one. I'm sort of scared, given how easy this fix was.
Also changes basic pathfinder behaviour. It will now stop moving/output null as the direction if it can't see its target, instead of continuing moving in the same direction. Might remove this if people don't like the change.
Ports Polaris' integrated electronics system, whichallows for Roboticists & Electricians/Engineers to build custom devices and machines for a variety of purposes.
