Allow mappers to set r_water and server admins to add mapinfo ACLs
Server admins may need to set r_water 0 on specific maps to make them playable and/or fix rendering glitches, and it would be better if that could be done without needing to hack qc.
Mappers see inability to set r_water as an arbitrary limitation. Players and admins may disagree via g_mapinfo_settemp_acl.
