PURPOSE
Improve use of SMS. Followup of merge 4287481bf0 .
SPECIFICATIONS
Currently when sending an SMS through the UI a message is posted using the
comment subtype. However it is better to lessen number of notifications
and log using the note subtype as it is mainly a log to know something has
been sent.
Order SMS by ID desc to ease finding them in technical menu.
Mail, sms: fix wording of mail / SMS failures
