[Issue #624] Make the JsDoc in Block Comments warning able to be controlled by the setWarningLevels method

See Issue #624 for the related issue.

Basically, I needed to be able to disable the warning for JSDoc annotations in non-JSDoc block comments. This exists in some older libraries that my team uses. I decided that this fit well in the "nonStandardJsDocs" group since its indicative of non-standard behavior.
