Added a setting for SERVER_EMAIL and a note in the deployment README
Added a note to the deployment doc about choosing the correct
TRANSACTION_DIR setting
If multiple jobs submitted to the same transaction use scripts with the
same name, the submit view appends a number to the name of the script to
prevent overwriting one file with another that might be different.
However, there was a bug that caused the view to then always execute the
first script.  This change fixes that.
