addressed a potentially infinite loop in astop.
configure options in README, creates traced and astop
minor improvements from testing -- astart and astop return 0
added hop-by-hop ack for cleartext messages (untested)
made priority names more uniform
added ALLNET_ in front of the names of the time constants
key exchange tested successfully
all packet initialization now uses init_packet, create_packet, or create_ack
chat and key exchange beginning to work, still bugs and lots of debugging messages
Install headers into $prefix/include/allnet

Also fixed: cipher.h was listed twice and caused
an overwrite error during install
