main: acthandler responds with vs and rc as strings instead of ints

In the JSON response from actHandler in main.go the varsum (vs) and reconfig (rc) should be returned as ints. They are currently returned as strings and this is causing issues. The issue for vs is when ns.Send() checks the vs it throws error ‘invalid vs’, and the issue for rc is that configuration just doesn’t happen properly since it doesn’t match expected values.
