Support for Windows

[moodmosaic]

I've converted a couple of QuickCheck properties to Hedgehog and they seem to be running fine on macOS:

However, when I try to run the same tests on Windows I'm getting:

*** Exception: <stdout>: hPutChar: invalid argument (invalid character)

---

In case it helps to troubleshoot, I used

• this Template Haskell splice to run the properties in both macOS and Windows
• GHC 8.0.2 on macOS and GHC 7.10.3 on Windows

I suspect it's the unicode symbols? The colours and in-place updates should get disabled because they're checking hSupportsANSI

I think the fix for this is usually along the lines of running hSetEncoding stderr utf8 before attempting to print to the console. At least I remember a similar bug being resolved in the purescript compiler that way.

Nice, I'll give that a shot

I may be able to give this a shot as well, over the next few weeks.

I think we can treat this as a dupe of #110 - the discussion there is a little more thorough, so let's keep that one open and close this. Reopen or file a more specific issue if more Windows problems emerge.
