* Rename `realmlist`.`color` field to `realmflags`
* Client 2.x and later support show in realm list supported
client version for specific realm.
For client 1.x this implemented by adding version to name
in similar way as it look in more recent clients.
For enable version show each affected realm must have in `realmflags` set
flag 4.
For realm work with not officially supported builds (build > last suported)
will show version 0.0.0 and correct build value.
