JHT ===> Moved MAJOR_VERSION and MINOR_VERSION defines to smb.h

JHT ===> Moved MAJOR_VERSION and MINOR_VERSION defines to smb.h
	Made version info consistent in ipc.c and nameannounce.c
	Added define for BROWSER_ELECTION_VALUE and BROWSER_CONSTANT
	(see do_announce_host() in nameannounce.c).

	Sniffing with the latest bloodhound I found that the byte range
	occupied by the BROWSER_ELECTION_VALUE is interpreted depending
	on the type of announcement being made.

	In a Local_Master_Announcement it is BROWSER_ELECTION_VALUE
	but in both Workgroup_Announcement and Host_Announcement
	this is seen as Comment_String_Pointer. What does this mean?
	We need to know?
