#1987 combined fix for 4.2 (#2030)

app/fax/app_defaults.php:
+ fix: duplicate check only within same default_setting_category.  This fixes the bug where "keep_local" for fax wasn't being created because there was a "keep_local" for voicemail.  Without this fix you will get a lua error due to the field not being set and nothing shows up in the sent faxes log.

fax/fax_log_view.php:
+ fix: back button text is missing.  Copied correct localized text code from another fax page that worked.

app/fax/app_config.php
+ fix: date field is now timestamp for postgres+mysql.  This fixes the listing only showing the date, not the time as well.

Note: app->defaults doesn't change field types.  Existing installs will have to manually update the field type e.g. for postgres:

sudo -sHu postgres
\d fusionpbx
alter table v_fax_logs alter column fax_date type timestamp without time zone;
\q
