previously, we imported nested modules together within
one module, (using nesting to distinguish between submodules)
possibly leading to very large modules
now, submodules can be broken up on import using the
"Select Content" dialog
test plan:
* import the Common Cartridge package referenced in the ticket
using the "Select specific content" option
* use the dialog to navigate the module tree and select
specific sub-modules
* if all sub-modules of a given module are selected, a
radio toggle should appear to choose whether to import
the module as one or to split them up
