User:River/hyacinth db split

We will shortly split the existing s3/s4/s6/s7 server into one server per cluster. All user databases with a cluster or wiki name in their names will be restored to the appropriate cluster; all others will be restored to s3 by default. If you have databases that should be restored to a different server, list them here.

s3

 * All databases.

s4

 * u_krinkle: Currently talks with commons from u_krinkle on sql-s4-user.toolserver.org
