------------
- Added EntryPoint class as another way to assemble functions (issue 59).
- Added support for Python 3.4; dropped support for Python 3.3
(this doesn't mean that Argh is necessarily broken under 3.3,
it's just that I'm not testing against it anymore).
- Shell completion warnings are now deprecated in favour of `logging`.
- The command help now displays default values of all arguments (issue 64).
- Function docstrings are now displayed verbatim in the help (issue 64).
- Argh's dispatching now should work properly in Cython.
