Simplify caching of modules from %run-ing scripts....

Simplify caching of modules from %run-ing scripts. Previously, we cleared and re-used a single FakeModule instance in which to run cells, and cached copies of the modules' namespaces to prevent them from being cleared. Now, we cache one FakeModule instance per script file, clearing it and re-using it if the same script is re-run. This seems more robust. Closes gh-3547
