[Dbix-class] Storage::DBI::Replication

[Norbert CSONGRADI]

I created a branch for replication support in DBIC 
(http://dev.catalyst.perl.org/trac/bast/browser/branches/DBIx-Class/replication).
The new Storage module (Storage::DBI::Replication) supports replicated data 
sources: one master database and many slaves.

Please check it's documentation on details how to set up and use it.
We use it in production enviroment with MySQL. If you could test it with other 
databases or could test transactions, please report me any success or 
failure.

For me, currently the only missing feature is the handling of replication lag. 
In non-DBIC enviroment, we added a flag to the database handler "urgent" 
which forces using of the master database handle for any kind of operations 
(both write and read) for the current session. Is it acceptable for DBIC in 
your opinion?

More documentation, code cleanup, and tests are on the way...
