[Building Sakai] Read Committed

[Ethan Kromhout]

We have been dealing with some performance issues in our MySQL instance 
for Sakai, and have been reading about the possibility of setting our 
isolation level to READ COMMITTED. A comment I found in a Jira noted 
that your binlog-format needed to be row for replication, but I didn't 
find much other comment about this change.

I was hoping to hear from others as to the safety and benefits of using 
READ COMMITTED for Sakai.

Thanks,

Ethan
