0.8.1 (2014-03-30):
- Detect the declared encoding in Python 3.
- Do not report redefinition of import in a local scope, if the
global name is used elsewhere in the module.
- Catch undefined variable in loop generator when it is also used as
loop variable.
- Report undefined name for `(a, b) = (1, 2)` but not for the general
unpacking `(a, b) = func()`.
- Correctly detect when an imported module is used in default arguments
of a method, when the method and the module use the same name.
- Distribute a universal wheel file.
