Move version header into a common direction to better reflect what it is.
The version header isn't really associated with lwlib itself since that is
intended to be some generic type routines that can be used by other
programs. It is, however, directly associated with lwtools. Thus, it should
be related to lwtools itself rather than the more generic lwlib.
