comment blocks are getting noPaintDefinedInParsers class

comments are highlighted fine, but not block comments. i think its a blobParser. if blobParser is set, i dont think we highlight the atoms (but we should at least allow a parser to define what atom type they should be painted with)

perhaps we need to paint blob atoms with a blob class?

Start by tracing the blobParser handling and the noPaintDefinedInParsers class to find why block-comment atoms are not painted. Confirm how regular comments are highlighted, then make sure blob atoms can receive a parser-defined paint class and verify that block comments are highlighted.
