Commit e0c7228d by E. Kolpakov
Options

Quality, safe template linter and test fixes: 

* Safe template linter reports zero violations on modified files
* Removed some (or most) coffeescript-genereated returns
* Big HTML chunks in JS converted to underscore templates
* Markdown processor - safe tempate linter compatibility
* Fixed double escaping HTML tags in code blocks caused by passing it through postMathJaxProcessor twice
