Fix and/or suppress JSHint violations in markdown.js 

This code is in pretty poor shape. Some lint violations
were easily fixed, others will require larger refactoring
of the code. Before that can be done the existing behavior
needs test coverage. For the moment this commit suppresses
the lint violations.
