Toggle-able compass icons

[kasperbjerby]

This one may be hard, especially if you actually moved away from a hard coded frontend as I suggest in another issue, but it would be nice if there was a way to select what waypoints that show up on the compass instead of just all, so just could toggle them somehow, the most clean solution would be if it integrated with the frontend map mod and made new buttons and all kinds of stuff, so I can definitely see why it's not a feature at the moment

A quick and dirty way to do it might be to have a config setting that is an ignored color.
