Moved the Python demo

[Philip Van Hoof <spam pvanhoof be>]

I moved to Python demo to tests/python-demo. 

The libtinymail-test directory now contains nothing but the GUnit unit
test library.

Other test will be added to tests. Including some small clients that
will use the account on mail.tinymail.org for gathering statistics and
testing purposes.
