By setting guest_name, guest_email, guest_location, or guest_referral to any
truthy value, a prompt will be display. By setting it to a string (instead of
true), that string will be displayed. I'm not sure how I feel about this kind
of tri-state setting (true/false/string), but it does reduce the number of
settings/options. The alternative is to have a separate boolean and string
setting for each prompt (which I first considered).

So, as of now:

guest_name = false <- no prompt for Guest's name
guest_name = "" <- no prompt for Guest's name
guest_name = true (the default) <- default prompt text for Guest's name
guest_name = "Enter your name, dude" <- replaces prompt text for Guest's name

For enter trailing white-space and ctrl-a codes, use string literals, e.g.
guest_name: "\x01hEnter your name, dude: "

guest_name = false will disable name prompt
guest_email = false will disable the email address prompt
guest_location = false will disable the location prompt
guest_referral = false will disable the "where'd you hear about this BBS" prompt

Note, at minimum, I do recommend prompting for the guest's email address so that if they send the sysop feedback (e.g. ask a question), they at least have some hope of receiving a reply.

Eliminate some of the infrequent SPAM posts to the SYNCPROG conference. Maybe make this behavior configurable?

If anything, I suppose would be beep if a search fails, but really, I think beeps are kind of annoying these days. Not changing the currently selected/viewed user is likely all that's really needed to indicate a search failure.

Helpful for debugging issues with this forgery detection logic (if there are any).

When setting the value of a message's 'can_read' property, ignore the PRIVATE message attribute (which is sometimes set in FTN netmail messages) since it's assumed all messages in the mail base are private, no special destination (to) name matching is needed here.

This only popped up recently via msglist.js because of the recent addition of checking each messages's 'can_read' property.

Apparently required by some news servers.
As requested via IRC:
<poindexter> Hi all, I've got a weird request. I'd like to post to a newsgroup that relies on automoderation. You need to add an approved: header to any posting to have it be accepted - keeps the non-techie riffraff away. is there a way to do that with newslink.js?

Should fix unvalidated/moderated message readability bug reported by Phil

Fixes issue #276

822header.js adds an enumerable method to the header object which ends up in the output when using the -hdrs option/command.

This addresses issue #277

Note: this is not actually a supported or documented script.

Thanks Coverity! (CID 332340)

It's anticipated that this will be used for JS-populated file metadata in JSON format in the future (and not just "archive contents" in .ini format).

Also, fix the double-free issue that was occurring when moving files with extended file descriptions (sbbs_t::movefile()). This was actually the primary problem I was fixing here, but noticed the metadata issue: metadata would not have been moved along with the other file info between bases.

Constified function arguments. Source path is still case-insensitive, but destination is case-sensitive (hopefully that's not an issue).

When a "move" (!copy) is requested, a rename() is always attempted first and if successful, job done. Otherwise, we continue on with the file-copy (and then remove).

This should resolve CID 332219 (DEADCODE).

Not that it really matters, but perhaps it'll matter in the future. And the code reads better.

Hopefully this helps get to the bottom of Ragnarok's reported problem creating ZIP QWK files with libarchive.
