Release 1.0: Support PEP 440 pre-release versions (backwards incompat…

…ible!)

Since the previous release (0.25) I've only made bug fixes
(i.e. no features were added) however the change related
to paylogic#8 is backwards incompatible, which is why I've decided
to bump the major version number.

Release 0.25: Enable use of system packages for requirements

Release 0.24.4: Fix empty executables under custom install prefix

Refactor setup.py script (improves Python 3.x support*)

* To counteract a UnicodeDecodeError when setup.py loads
  README.rst to populate the `long_description' field.

  Could have fixed this with a two line diff, but noticed
  some other things I wanted to improve, so here we are :-).
