Checked in.

To add a new subtree type, just add a

	static gint ett_hello_sailor = -1;

at the beginning of your dissector (if there isn't already a list of
them there, add it after the "proto_" and "hf_" values), and add a
pointer to it to the "ett" array in the appropriate "register" routine. 
(Most if not all "packet-*.c" files already register subtree types; copy
the code in an existing one if the code isn't in your "packet-*.c"
file.)  It's no longer necessary to add it to a list in "packet.h" (the
list isn't in "packet.h" any more).

This should also allow dynamically-loaded "plugin" dissectors to
register their own subtree types.
