Better name for the attribute to prevent collision, add to #after_build #link was probably overly too broad, so I've renamed the attribute to include the module name. The code previously also fully took over #after_build, which killed other modules registrations. Now the module's a good citizen and only add its handler leaving the others as is.

name = Node Reference with View popups
description = Adds a "Search" link to nodereference widgets which use the associated view
dependencies[] = nodereference
dependencies[] = views
package = User Interface
core = 6.x
