Package greet_client for consumption in travis suite #57
Description
We want to graft greet_client onto the repo(s) we're using for later versions of Kerberos. In theory, since there has been no change to the greet_client code since before the 1.10 release, it is not a problem to only test it there and we don't need to worry about 1.12 and 1.10.
This was originally blocking #54 though it has been decided to continue without explicit greet_client testing in Travis.
