Add the ability to have Errors reported by the plugin.
Having the ability to have the Errors reported like the Warnings would be very useful.
Currently some parsers may report errors but they are still listed as Warnings which is confusing to users who view the reports.
The simplest solution I think would be to just have users have to make their own parsers and then a flag to indicate if the type the parser is looking for is Warnings or Errors which would then modify the reports to says "Warnings" or "Errors" in all the appropriate places.
