Removed comma causing described error. Also corrected the class called for the configs.  Added plain stylist configs to environments/developement.rb. Templates changed to not call service_description as it does not exist. AppointmentsController updated to call both to_stylist and to_client.
Fixed small error with the stylist config naming.
Added the Letter Opener gem for the dev enviroment.
Fixed incorrect implementation of the iCalendar class.
