Add cross-project reference in composite application project.
Implemented in CB #903.
http://www.netbeans.org/issues/show_bug.cgi?id=96737 shows an example of cross-project reference working in compapp.
The following documents the current cross-project reference behavior in CompApp.
When adding a JBI Module into a CompApp, an implicit project reference is created. Since cross-project reference is not
transitive, the CompApp is not aware of any project that its constituent JBI Modules are referencing. This means when
creating new test cases in the CompApp, only WSDLs defined in the CompApp and CompApp's constituent JBI Modules are listed.
The following shows an example:
CompApp1: (has one JBI Module)
BPELModule1 (referencing BPELModule2)
WSDL2 (importing WSDL4 from BPELModule2)
In CompApp1, the following WSDLs will be listed:
WSDL1, WSDL2 (WSDL4 is accessible as part of WSDL2)
In order to create a test case for WSDL3, the user needs to explicitly add BPELModule2 as a constituent JBI Module into
