Early releases were not properly tagged in the SubVersion repository, so a revision number is listed instead.

Fix passing of dict parameter when creating reply packets.

add HandleAuthPacket and HandleAcctPacket hooks to Server class. Request from Thomas Boettcher.
Pass on dict attribute when creating a reply packet. Requested by Thomas Boettcher

packet.VerifyReply() had a syntax error when not called with a raw packet
Add bind() method to the Client class

This could be exploited by sending a number of bogus responses before a correct reply to make pyrad not see the real response.
correctly set Acct-Delay-Time when resending accounting requests packets
verify account request packages as well (from Farshad Khoshkhui)
protect against packets with bogus lengts (from Farshad Khoshkhui)
