Option to merge users

[TayouVR]

I have some people multiple times since they switched accounts at some point. It would be useful if I could merge them together in the graph.

I think the most user friendly way this could be done would be having a right click menu in the graph directly to rclick->merge from rclick->merge into or something along those lines

Great idea! I'll look into how this can be implemented!
