Added support for alternative output syntax in TestNG i.e. "expected […] but found […]"

Hi Cedric.
As we discussed, I have added support for the alternative TestNG output syntax, so this one now also can be parsed for side-by-side viewing.

I took the opportunity to rewrite the whole TestNG parsing method to use precompiled regex's instead of adding yet another "if" block. This should make it easier to add additional output formats in the future, and possibly allow you add support for configuring these locally? (properties file or preferences?).

I haven't had the option of retesting the syntax-forms that my own testNG doesn't provide, but I have done my utmost to match the regexes with the same strings as previous.

Hope it works out.

Thanks, Jan.

A minor thing: the way you initialize the static map is not thread safe, you usually want to synchronize around it (I don't think it's an issue in this case since it's unlikely the user will run two of these in parallel, but just FYI).
