Support for a 3rd line of RESULT.ED drop file (from external message editors):

Full editor name and version details (up to 127 chars), for use in the EDITOR
msg header field which is propagated over QWK networks.
From what I could find, the WWIV RESULT.ED file format only ever contained 2
lines:
<Anonymous: 0/1>
<subject>

So adding support for an optional 3rd line should be fine and backwards
compatible. Hopefully WWIV or its message editors don't define a different
"standard" 3rd line in the future. :-)
