Description

Add support to the rails app for reading from multiple separate mysql hosts while writing to a single mysql master. Specifically using a modified version of mysql_replication_adapter. the original can be found at http://rubyforge.org/projects/mysql-replicate/ The specific modifications are to default to using the slaves instead of requiring that you explicitly mark a query as to be directed to a slave.
