Add JS bbs methods: save_msg_scan() and reload_msg_scan()

These methods aren't normally needed (msg scan config/ptrs are
automatically loaded upon logon and saved upon logoff), but for users
(e.g. sysops) that can be logged-in concurrently or experimenting with
scans, these methods can be useful and I plan to expose in a loadable
module next.
