many many netclient/frondent changes (just the beginning though): * better separation of concerns * trying to reduce segfaulst due to netclient being deconstructed while still in use * no extra popup for quit reason anymore * errors/warnings will be displayed in chat instead of popups in most cases * NOTE: auto-kick for ignored players is currently _disabled_ will fix that soon
