Tweaks suit sensor menu to be easier to use

The suit sensor cycle system is garbage. You can't move while adjusting suit sensors since your object verbs jump around like fucking crazy anyway. So this changes them to a popup which shows what your current suit sensor setting is when you open the menu. Yes, popups are cancer, but this is MUCH better than a stupid cycle system which makes 99% of people ignore the fuck out of their suit sensors since that system can be seriously affected by lag.
