Adding Examples and More Verbose Output

I added examples and changed the fail message to include the full output so that users can see the failing case.

New output of example:
```
Running 1 test suites...
Test suite example: RUNNING...
Test case FailingProperty: Fail "*** Failed! Falsifiable (after 1 test):
\n0\n"
Test case SucceedingProperty: Pass
Test case SometimesPassingProperty: Fail "*** Failed! Falsifiable (after 2
tests): \n0\n"
Test suite example: FAIL
Test suite logged to:
dist/test/cabal-test-quickcheck-example-0.1.0.0-example.log
0 of 1 test suites (1 of 3 test cases) passed.
```
