[PATCH] Allow name template in --test-option and --test-options

Here's a patch that implements http://hackage.haskell.org/trac/hackage/ticket/787 Tue Jan 11 08:30:13 CET 2011 Johan Tibell * 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?
