Micros~1 shortened paths in the drop files. Another fix for installations to
e.g. "C:\Synchronet"

- returns true/false if the user's terminal supports all the passed flags
- returns the supported flags if no flags are passed for comparison
- automatically uses the auto-terminal-type flags if no user is logged-on

this and do *not* write to the hungup.log file.

* Using SAFECOPY for buffer overrun protection.

If "Intercept Standard I/O" is enabled, Line1 becomes:

If not, Line1 becomes:

ie:

Currently, this is #ifdef'ed out since I'd like DMs approval before I do
this.

propogated to the call to external(), so this optional feature did not work.

timeleft (in seconds) with the configured max time (in minutes) and
setting the amount of time allowed in the door to max time, so a user
could easily get extra time in a door if the max time option was used.
Enforcing 15-bit time left (in seconds) cap for chain.txt (WWIV) doors, works
around doors that interpret this value as a signed 16-bit value.

pause is forced when an online external program (door) exits. Default is off.

Work-around: limit time-left value to 15-bits (9+ hours) for DOOR.SYS doors,
fixes old 16-bit doors that read this value into a signed 16-bit integer and
won't run correctly or at all if the value is "negative".

Added support for Door32 doors that use stdio instead of sockets.
Added support for Unix Door32 doors that use sockets (are there any?).

Real name option now works for DOOR32.SYS doors too.
