#814: Avoid orphan flexible instances in Cabal-TestSuite documentation

The example code shown in
http://www.haskell.org/cabal/release/cabal-1.10.1.0/doc/users-guide/#test-
suites
needs FlexibleInstances, and the instance is orphan, too.
Although this code is not intended to be used in most packages,
it still looks like those instances are necessary or at least good style.
I suggest to replace the generic pair by a custom data type like
{{{
data TestCase = TestCase String Bool
instance TestOptions TestCase where
...
}}}
in the documentation.
Since Cabal is a widely used library, it has automatically an educational
aspect.
