@Deuce should review this.

CONTINUE is like GETKEY except it'll set the display-abort flag if 'N' or 'Q' are typed.

Make the WAIT:<n> argument 10ths of a second (instead of milliseconds) to be more consistent with DELAY:<n>.

GETKEY waits indefinitely for any key press by the user (resolves issue #245).
WAIT:<n> waits for up to n-milliseconds for a key press and then continues on.

For both cases, the key pressed is not echoed or acted upon in any way. Ctrl-keys could be handled by global or built-in ctrl-key handlers, so those would be the exception.

And make it the default for newly created sub-boards.

This won't impact Synchronet as it has a separate signal handling
thread, but we still need to behave properly for processes that
don't.  I'm also saying that ENOMEM does not indicate a disconnection,
though it may be better to pretend it was disconnected...

The DNS_blocking class supports the same API as the DNS class, but
does not use events, so any method will complete before returning.
As such, the callback argument is optional.

js_callback_t was not being properly retreived.

Not having that dependency is the entire point of it.

Sheesh.

SRV, NAPTR, and URI

Thus appears to have been the root cause of the infinite loop/memory
issue.  Basically, line was never replaced if it didn't match
^{[0-9]+}$ and didn't result in a number when passed to parseInt()
This resulted in an infinite loop that kept pushing zero-length
strings into an array.

Implicated in possible infinite loop/OOM problems.

a sub-board that has polls disabled.  This fixes an issue where SlyVote was showing all
available message groups but some could be empty due to having no sub-boards that allow polls.

Implement support for callback style programming

This appears to work and the event handler *should* work on other
event types already.

Note, this is *nix-only due to the use of poll().  select() will
need to be used for Windows to keep XP compatability.

Broken with the poll() update
