ability to exclude tests by name at runtime

[edgimar]

There are the run and runlist commandline arguments that can be used to specify what tests to include, but it would be nice to have a norun argument (or a syntax in the case of runlist, like a '-' prefix) that can be used to indicate tests to exclude at runtime.

You can exclude by using categories, but it shouldn't be too hard to modify run/runlist to accept a '-' prefix - TNameFilter.Match would be the place to look at for that. Unfortunately I don't have time to work on this right now but will accept a pull request with this.
