Added some simple argument validation for functions just to prevent some useless calls to the BGG API; functions return None instead of raising an Exception when some object is not found (e.g. user)
Improved __str__ and __repr__ of objects
Got rid of some __str__ methods to avoid the Unicode madness... nobody should need them anyway
Fixed Collection._format, there's not iteritems anymore
Updated unit test
Updated documentation
Updated version
Trying to use coveralls.io
