handy WoW-macro's

A macro that tells you if your realm is connected to other realms and lists all connected realms:
```
/run local realms = GetAutoCompleteRealms()  s="" if(realms[1]) then s="\nConnected Realms:" for k, v in pairs(realms) do s=s.."\n"..v end else s="Your realm is not connected." end print(s)
```

to know on which realm you are after joining a (farm-)group.
edit in 2023: this doesn't gives you the realm you phase to, just the realmname your toon is on:
/run local realmName = GetRealmName() DEFAULT_CHAT_FRAME:AddMessage("You are currently on realm: " .. realmName)
