Got `rails s` to work on development machine

rmail is a very old gem. I'm not exactly sure what it was being used for because Ed commented stuff out but we will see.

Also deleted all migrations (because they are not canonical and not necessary at this stage of development) and dumped a database schema from psuedo-production which has been judged to be canonical.
Removed old site (that's what branches are for!)
Removed secret token from source control

Also now application2 layout says "DEVELOPMENT ENVIRONMENT" when running on dev
