From Wes Hardaker:

	Define HAVE_SOME_SNMP if either HAVE_UCD_SNMP or HAVE_NET_SNMP
	is defined, and use HAVE_SOME_SNMP, rather than HAVE_UCD_SNMP,
	in most places when testing whether we have an SNMP library or
	not.

	Be more selective when including Net-SNMP header files.

Fix up {gtk,gtk2}/main.c to do the same SNMP stuff that tethereal.c
does - including the MIB stuff that gtk/main.c was doing but gtk2/main.c
wasn't doing.

Fix the copyright date in gtk/main.c.
