Rename archivemail.py to archivemail

On Unix, most scripts don't come with a file extension, it's not needed, and
we distribute the script as "archivemail" anyway.  And most importantly, I
like it better without the extension. :)

With a little trick we can still load the script as a module from the test
suite.
