[Johan Tibell]

I've created a patch that implements

    http://hackage.haskell.org/trac/hackage/ticket/787

and attached it to the ticket.

 * Allow name template in --test-option and --test-options

 Only $test-suite is supported for now.

Things to discuss:

 * Which templates placeholders should we support. I only added
$test-suite. Supporting all of the placeholders supported by --log
will require some refactoring as the placeholders are computer *after*
the test has been run, using a file output by the test executable.

 * Is it OK to use PathTemplate for template strings which aren't
necessarily paths or should we introduce a new Template type?
