Add wireshark and tshark after repocopies from ethereal and tethereal
respectively. Wireshark is a rename of ethereal after the principal
developer moved companies and lost the Ethereal copyright.
Messenger, don't shoot!
Now the ethereal binary is called wireshark, the tethereal binary is
called tshark, and idl2eth is now idl2wrs. All other binaries have
kept the same name.
In addition to this name change, I have also changed the PREFIX from X11BASE
