Bug 42766: Add ScriptLog system preference

Adds a new YesNo system preference 'ScriptLog' in the Logging section
of system preferences, adjacent to CronjobLog. When enabled, the start
and end of non-cron Koha scripts (those using bare 'use Koha::Script'
rather than 'use Koha::Script -cron') will be recorded in the action
log under the SCRIPTS module.
