[Suggestion]: Add a unique ID variable for better tracking

[westor7]

Hello,

I see that feature has been requested a lot of times by a lot of users (plus me), it can be a useful addition because it will solve either some spammers situations, like even if someone changing his IP or switching browsers he would not be able to connect/join on the network/channel from his PC if using that feature, serious networks supporting realname bans either.

Creating a way on WIG to allow set %d under [Clients] that would be a unique ID of that PC, that this Unique ID could be a combination with Environment Variables of the system or something more clever.

Config Example:

[Clients]
username = "%d"

or

[Clients]
realname = "Personal ID: %d"

or

[Clients]
hostname = "my.personal.%d.id"

• Thanks!
