Merged client mailer method into appointments_mailer.rb and renamed to appointment_mailer.rb. Also updated to use correct Appointment class attr names.
Mailer templates renamed to new Appointment to_client method name and duplicated for to_stylist method, along with removing unused templates.
The to_stylist method was changed to use config.stylist_email_address for delivery address.
