Cloning Packages should allow for Generators to be cloned.

[profcturner]

At the moment, cloning supports the deletion of generated activities. However, it does not clone the generators.

• an option for cloning generators would seem helpful
• we may want to link the cloned sets to the cloned generators rather than the originals

It's worth noting that without this, deleting a generator in a past package might cascade delete generated activities in later packages.
