Currently, the JDT launching support considers "container" entries on the 
classpath to be duplicates if their ID (first segment) matches. However, this 
has turned out to be "too agressive" for WSDD, as WSDD has one container ID 
that maps to many different libraries. The result is that we remove entries 
from the runtime classpath, which are required.

The proposed solution is to define a new interface which identifies 
duplicate/redundant entires on the classpath explicitly. The interface, when 
implemented by the associated IClasspathContainer, will be queried to determine 
if it is a duplicate of an existing entry. 

When a container does not implement this interface, the existing algorithm will 
be used (i.e. equal IDs indicates duplicates). This addition does not change 
any existing implementations (as the old behavior remains the same).
