Fix broken links in ajdoc. Part 4 : fix links to members of types

in other packages (again). Also, fix for nested types. Covers more than one
level of nesting. NOTE: the tool is currently not capable of producing
output for more than one level of nesting. Bug will be raised if Ron has
not already opened it.
