Print re-check information if the source is not found

[peddie]

If I run my hedgehog tests from the wrong directory and they find a failed property, the program immediately dies with an exception from openFile. This is a shame if my tests have been running for a couple hours -- would it be possible to print out the recheck information (size and seed values) no matter what happens with the source rendering? Then I can just move to the right directory and call recheck.

This problem is less bad once I can set the seed manually, but as it stands, hedgehog may find failures I can never replicate.

I think this has been fixed in recent versions - see #184.

Feel free to reopen if that is not the case!

Specifically, hedgehog-0.6 or higher.
