More helpful exception on connection errors (fixes #11)
Removed executable bit from python modules
Made module names more pythonic

Module names are now written using under_scores according to PEP8.

The module `blockID` has been renamed to `blocks`. I think `from blocks
import WOOD` is the most natural way to import a wooden block. An
alternative would be `block_ids`.
Cleanup (mostly PEP8)
Added AUTHORS.md
Removed util.py
