Bump cabal-version?

[asayers]

Hi @luite,

If ghcjs-prim requires Cabal >=1.22 to build, is there a reason the cabal file specifies cabal-version: >=1.10? I was having an issue installing GHCJS, and bumping this number to 1.22 solved it.

---

For completeness, the issue was that even though Cabal-1.22 was installed, cabal-install was trying to use Cabal-1.18 for some reason:

Configuring ghcjs-prim-0.1.0.0...
Building ghcjs-prim-0.1.0.0...
setup-Simple-Cabal-1.18.1.5-x86_64-linux-ghc-7.8.4: dist/package.conf.inplace:
inappropriate type

I bumped into this issue too.
cabal-version: >=1.22 in ghcjs-prim.cabal helps.

When building ghcjs-prim with GHC, cabal 1.22 isn't actually required. There were some issues with earlier releases of Cabal 1.22 that might have caused this ('inappropriate type' is likely some problem where cabal expects a directory but gets a file (or vice versa))
