fcdb: allow database.lua to set user's cmdlevel, delegation etc
Jacob Nevins <jtn>:
"An obvious extension for an authentication database would be to store access levels (cmdlevels) in it. I don't think this is possible with the current fcdb arrangements, however, as database.lua has no way to cause the cmdlevel to be changed.
The obvious thing is to give the script access to issue arbitrary server commands such as 'cmdlevel' (assuming we open up the security model per bug #19729). However, at the point where the script is naturally invoked (checking credentials), it's probably not practical to do this, so there'd probably need to be a further callback into Lua once the connection structure was set up and the server could accept further commands.
Delegation feels like something that could live in a database, too. However, this applies to players rather than users, so I'm less clear how that would work precisely. Possibly the script would need access to game structures (patch #3385?)"
