Mark them all "UNUSED"

Fixes unnecessary [Hit a key] prompt.

This appears to work around a bug in BRE, FE, and TAL where they don't
recognize the "1" (ANSI supported) unless there is at least one other
character on the line following the decimal digit, resulting in the
unnecessary prompting of the user:
  This game is much more enjoyable with ANSI graphics enabled.
  Do you want ANSI Graphics? (Y/n)

As reported by "ben" in IRC.

Fixes issue #645

Fix-up the require() statements.

Also clear the screen immediately cause it can take a noticable amount
of time to read/parse the file.ini and main.ini files.

When used, replaces built-in user (e.g. terminal) settings menu with a
loadable (e.g. JS) module.

... or else any changes we make aren't saved (we're just modifying this
object in memory).

Fix the heading (user alias is displayed, not name).

Fix the mouse hot-spots.

Fix the "None" default download protocol (requires latest text.js).

Fix the hot-key option (inverted logic).

Don't display the [K] Command Shell option if there's only one available.

I finally reproduced this issue myself on a fresh install on Windows.

We needed explicit file closing here as going out of scope doesn't immediately
finalize (and close) a File object. That may not happen until garbage
collection and thus prevent subsequent re-opens of the same files, so always
close() your files.

init-fidonet.js calls install-binkit.js which uses cfglib.js, so that was
a source of these errors too.

This should avoid/work-around issue #630

Nelgin's terminal server log indicated that the node's configuration was being
reloaded for a new client connection (which doesn't normally/always happen,
only when there's been a config file change or a node "rerun" requested),
while there was still a user online using that node. This would explain the
segfault (configuration fields being freed and reallocated).

The node_socket[] array indicates when a node thread is actively servicing
a client, so it should contain INVALID_SOCKET for the any node's that WFC.
If it doesn't, that means something/someone changed the node's status value
to 0 (WFC) in the node.dab file while the node was still in-use. Let's not
crash in this case and rather just log the message and give the client the
next available node (if any).

Some of the errors could be pretty vague since they looked the same and
we were depending on the path/file attempted to be opened in the log msg
to clue us into what exactly was being attempted. But some of these file
paths are sysop-configurable, and they can put unexpected things in there
that make it difficult to determine exactly what file was trying to be
opened and for what purpose. This should help a little bit.

This allows the calling script to control what the default item is (when the
user just hits enter), and not always the first item.

IIRC, the error was undefined has no properties or split() is not a function,
something like that.

tbz is technically still supported by create_archive(), but without it
being included in the supported_archive_formats definition, isn't easily
chosen as an option and nobody seems to miss it.

Apparently one was copied from the other and used the same original
output file subdirectory name ("upgrade") oops.

I didn't notice that these projects were still being built with a toolset
that didn't target WinXP. I might need to update the SDK too.

Also, although not a bug (because we re-read/parse the user's record every
menu cycle), don't decrement user.xedit before calling uselect()
- just not a good practice to not modify variables unnecessarily.
See the corresponding change to exec.cpp, which was a bug.

This bug would leave the user's external editor setting decremented by one if
they aborted (with Ctrl-C).
