Anonymous Contact Service software changes

1.0 - 1.1

Changed file names to bring them under the
14 character limit some inferior operating systems are still saddled
with, and reposted as shar files because some inferior operating
systems don't have the necessary tools to deal with uuencoded compressed
tar files. The net can thank Rich Salz and his makekit package for the
latter concession to antiquity.

Modified unspool to dump anything after a line containing "--" as 
signature, rather than insisting on the standard "^-- $" signature
tag.

Added "rebuild" script to system - takes output of listr2a and
rebuilds the real2alias database from it.
