[engine] Capture the `resources=globs` argument for Python targets
Review Request #3979 — Created June 7, 2016 and submitted
This fixes #3506, which is caused by our conversion of the
globs/rglobsobjects without capturing them later.
- Capture the
resources=globsargument for Python targets
- Open tickets to design the migration path to typed Sources
Fixed the clobbering of the parents sources field (which wasn't being detected due to the subclassing of Struct).
