Warnings in terminal about constraints

[JamesLongman]

After the constraints were updated in #8, xcode terminal now appears to be showing huge error messages upon views loading stating that some constraints cannot be complied to.

Layout seems fine and tracking down the particular constraints causing this will probably be a big job so I'm happy to leave this issue open for the release version and possibly fix this in a later patch
