feat(net): CDCLIENT_RELOAD master message

Browse Source 
Appended at the end of MessageType::Master (46); the pin test is updated.
With names it tells a server which fdb copy and CDServer.sqlite to switch
to; without them it asks master to check the client's fdb now.

* CDCLIENT_RELOAD payload.
*
* Master -> every server: the client's cdclient.fdb changed. fdb and sqlite name the new copy and its CDServer.sqlite
* in resServer (FdbSnapshot.h); each server switches to them between frames.
*
* World or dashboard -> master, with no names: check the client's fdb now (a GM's /reloadcdclient or the dashboard).
* requesterId is the character who asked (told the result in chat), 0 for the dashboard.
