History
Jim Mussared 86ce442607 ports: Add '.frozen' as the first entry in sys.path. 
Frozen modules will be searched preferentially, but gives the user the
ability to override this behavior.

This matches the previous behavior where "" was implicitly the frozen
search path, but the frozen list was checked before the filesystem.
