Feature requests, groups, users, strict network

[liquidox]

Feature requests:

• I would like to be able to link a Gate type to a network (allowed-networks=central,Towns,George) Without this, the next options are kinda pointless I guess. Or perhaps a flag (strict-network=true), which makes the Gate only work on the network the .gate file is named after (Towns.gate) for the Towns network.
• I would like to specify a Gate type can only be created by specified groups (and inheriting groups) and/or players: (allowed-create-groups=Builders, allowed-create-users=George)
• I would like to specify a Gate type can only be used by specified groups (and inheriting groups): (allowed-use-groups=Peasants, allowed-use-users=Peasants)
