Multiple improvements to tab completion....
Multiple improvements to tab completion. I refactored the API quite a bit, to retain readline compatibility but make it more independent of readline. There's still more to do in cleaning up our init_readline() method, but now the completer objects have separate rlcomplete() and complete() methods. The former uses the quirky readline API with a state flag, while the latter is stateless, takes only text information, and is more suitable for GUIs and other frontends to call programatically. Made other minor fixes to ensure the test suite passes in full. While all this code is a bit messy, we're getting in the direction of the APIs we need in the long run.

def tarModule(mod):
"""Makes a tarball (as a string) of a locally imported module.
This method looks at the __file__ attribute of an imported module
and makes a tarball of the top level of the module. It then
reads the tarball into a binary string.
The method returns the tarball's name and the binary string
representing the tarball.
Notes:
- It will handle both single module files, as well as packages.
- The byte code files (\*.pyc) are not deleted.
- It has not been tested with modules containing extension code, but
it should work in most cases.
- There are cross platform issues.
