memcpy calls and explicit setting of fields to 0) - this code is just bad.
The only functional change should be that the SBBSecho product code (0x12FF)
and major/minor version number is now added to headers of type 2+ packets
generated by SBBSecho. Type 2 and 2.2 packets will have just 0xff for the
product code and the SBBSecho major version number in the product "serial
number" field (as is the common practice). I guess everyone's using type 2+
packets these days? You don't get 5D addresses with 2+, but SBBSecho doesn't
really do anything with 5D addresses anyway. <shrug>

Print wanring if type 2+ orig/dest zones don't match the zone fields in the
type-2 portion of the header.
Updated some pkt header field names in fidodefs.h.

system's address was being added to SEEN-BY list twice when destination zone
was different than the system's zone.
Another experimental change for Joe (1:249/303) and Wilfred: when parsing
SEEN-BYs from incoming packets, assume the zone of the nodes in the SEEN-BYs
is the same as the origin zone of the packet, rather than the destination zone
of the packet.

Removed 'getmessage' condition (would call printMessage from forum.ssjs, which wasn't used, didn't work, and has been removed.)
