If the file from a TIC already exists, use wildmatch() on Replaces to see

if it should be replaced.  It's common on FidoNet for replaces to have a
wildcard in it.

Also, add support for a new Handler key in tickit.ini.  This defines a file
which defines a Handle_TIC function and whose last statement isn't null.
The parsed TIC file is passed to this function and, if it returns true, the
file is assumed to be handled.
