Change Sonar to Rangefinder across Wiki

[OXINARF]

While looking at Auxiliary Function Switches I saw that it still mentions Sonar instead of Rangefinder and there are other places in the wiki doing the same. It can't be a simple search and replace though as in same places sonar is correct (when describing actual sonar devices, for example).

Probably best to leave this one open at the moment, until a proper scan is done to check for instances.
