Bug 19178: Remove outdated sms/* scripts and related files

Bug 19178: Remove outdated sms/* scripts and related files

Those files appear unmaintained and unusable with current
Koha and should be removed.

It appears at some point there was work done on a feature
to send SMS messages to a phone number using a form in
the tools area.
This has never been documented, files and git history
make it look like work remained unfinished.

sms/sms_listen_windows_start.pl
- targetted for Windows, which is not supported by Koha

00-strict.t
- reference to sms removed

sms/sms_listen.pl
- refers to a table sms_messages that doesn't exist
- uses getmember() that doesn't exist

sms/sms.pl
- script calls routines that no longer exist in SMS.pm
  error_codes(), parse_phone(), write_sms()
- template sms-home.tt is not accessible form anywhere
  in the templates

sms-home.tt
- see sms/sms.pl

Makes sense. 00-strict.t runs OK after applying the patch.
