[9746] Implement show realm version and build in realm list.



* 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.
