Title: Fix non-functional describe config lookup

The current version of `grunt.config.process` does not do a config lookup; it
simply processes a value, so `describe.dirtyMark` was always
"describe.dirtyMark".

Instead, call `grunt.config.get`.

Also allow falsy values for `dirtyMark` (the empty string, e.g.).
