1.4.4

An out-of-rhythm release to upgrade phantomjs-prebuilt to version 2.1.10. The 2.1.7 version used hitherto had a security vulnerability which is fixed in version 2.1.8 (of 26JULY) and later.

It also includes some features that have become production ready in the mean time:

• Improves error handling so error-messages (1) show up more often when
  something went wrong (2) contain something human parseable more often.
• package.json now excludes msdos & derivatives ('win32') as a
  supported platform - this is until #5 is solved.

All changes since 1.4.3: 1.4.3...1.4.4
