Filling in the missing pieces
Starting to remove email messages from DADA::Config and saving them into their own source files. Hurray!
Moving more messages out of the Config.pm
Removing more email messages from the Config.pm file!
This removes, I believe, all the email messages from the Config.pm file, and puts them in their own files, in MIME format. Hurray!
