I'm not too huge on adding an rc file for PyFITS if only because there
are only so many 'global' options it has to tweak.
EXTENSION_NAME_CASE_SENSITIVE is the only one right now.
On the other hand, adding such a file would open the door to adding more
options and configurable defaults, so it could be worth considering (in
addition to environment variables, for people who prefer to use them).
