pypandoc 1.3.3

Only fixes the build process on travis/appveyor to get a proper sdist on pypi

pypandoc 1.3.1

Fix sdist (1.3.0 contained the pandoc binaries)

Version 1.3.0

* Add possibility to use .lua custom writers as output format
  (thanks to @snay, JessicaTegner#109)
* pypandoc now also accepts URls (http+https) where it allows paths (JessicaTegner#108/JessicaTegner#115,
  thanks to @dufferzafar for reporting this)
* now downloads pandoc 1.18 (or includes that pandoc version in the prebuild
  wheels) (JessicaTegner#112/JessicaTegner#113, thanks to @TomAugspurger for reporting this)

Under the hood, we now also do CI tests on windows (via appveyor) and do PyPI
uploads from the CI services (see JessicaTegner#116/JessicaTegner#117).
