(4/5) Python3

[macfreek]

This pull request is branched after pull request #31; please examine that request first. (The comments below are only about commits ee4a69b to 0ba7890. Let me know if this is problem and you want me to rebase this.)

These commits simply include changes required to run the test and six examples under both Python version 3 and 2.6 (2.7 and 3.2 were tested).

The only thing that failed was the map example under Python 3 for the simple reason that there seems no Python Image Library (PIL) for Python 3 yet.

This closes #15.

PS: due to other obligations, the next pull request may again be delayed, just in case you're wondering were number 5 went :)

This can't be automerged, I'll merge it tonight.

By the way: I had no problems:
