OSX: strip does not work when forming a bundle. Fixed.
The underlying problem was that the BUNDLE class did not draw files
from the appropriate cache; it always uses the "00" cache. Now,
BUNDLE obeys the strip/upx flags that the input COLL or EXE object
has, which in turn depends on the command line options passed to
pyinstaller.
Log Message:
-----------
Changed initializations of upx and strip variables to True/False
as appropriate. Also keyworded the arguments to checkCache for
better explicitness.
