When writing/reading quotes.txt, ignore first 2 lines if WWIV-type

WWIV writes 2 lines of metadata to the beginning of its quotes.txt file created for external message editors. Its not clear yet what these lines should contain, but the first line apparently should contain a '#' character since BREdit checks for this character before deciding to throw-away/ignore these lines (don't use them for quoted text). Thanks mlong for this tip!

So if the external editor is set to "WWIV CHAIN.TXT" in SCFG (even if the door doesn't need/use it), then the quotes.txt file created by Synchronet will contain the extra 2 lines. We're just writing a # to the first line and the second line is blank.

This fixes reported issue #188.
