Lots of cleanup, commenting

js/markdown.js

-// FIXME: Nested blockquotes require blank line
-// TODO: HTML tags probably need better handling. Consider whether interior of matched tags should be interpreted as markdown.
-// TODO: Test broken/incomplete syntax thoroughly
-// TODO: Sanity checks on loops/recursion
-// TODO: Spreadsheet functions in tables
-// TODO: Support document differentiators for CSS identifiers (using markdown to render 2+ documents in the same page, need ids to be unique within the page)
-// TODO: Support language marker in ``` to at least add a CSS class to the <pre>
-// TODO: Better way to detect start of new block inside of list item without line break
