How I got Windows working

[ggreif]

Other things I observed:

• I had to apply this patch

• cmd = env['HOME'] + '\AppData\Roaming\cabal\bin\hyper-haskell-server' +cmd }

  // spawn process

• ~I still don't know how to start the interpreter reliably from HyperHaskell, for now I do it from another cmd console.~ It turns out I have no stack installed, and the Settings entry of my worksheet did not fall back to cabal. It works now when I manually set cabal without arguments.
• No HyperHaskell name set on the initial worksheet's name, I see "(untitled)" instead. It changes, though, upon loading of a worksheet.
• In the cmd console I cannot kill hyper-haskell-server by hitting ctrl-c.
• In Windows "Save" and "Save as" won't work.
• In Windows, when closing a worksheet, an exception happens.

"Save" and "Save as" won't work because of the use of a macOS specific function in the save functionality. #19 fixes this.
