Store timestamps for modules to autoreload...

Store timestamps for modules to autoreload Closes gh-4127 At present, autoreload compares the timestamps on .py and .pyc files. However, this can fail in a couple of ways (see gh-4127). With this change, it caches the mtime of the .py file when we loaded it. Some extra complexity is needed to store the mtime as soon as possible - we scan sys.modules when autoreload is loaded, and register a post_execute hook to check for newly imported modules after each cell.
