This has been implemented as in #2 with two changes. The lookup key is
the mime type for the static file not the file extension. Specific
file names can be added as keys and they take priority. Support for
setting the header for file or message content has not been
implemented.

I have not added support for managing an expires header.

I also added a new section to doc/customing.txt describing how to use
interfaces.py as that is used to configure Cache_Control.

Would somebody take a look through the new section and if you have
some other examples for interfaces.py feel free to add it or send me
patches.

Thanks.
