This implements sxmo_hook_smslog.sh which allows the user to establish
how logging looks.
We were also inconsistent on this: mms would set the contact names in
the logfile whereas sms ony gave the numbers and used a sed to convert
them.
I tought about setting this in sxmo_hook_tailtextlog.sh, but:
(1) processing on a tail is a PITA
(2) one can get the "raw" data for sms.txt from modelog.tsv.
I implemented a basic and a fancy option, but it is really up to the
user.
I also implemented sxmo_contacts.sh --name-or-number and so was able to
clear out the '???' code all over the place.
