Remove dangerouslySetInnerHTML

Was quite enthused to see this but turned out to be a wrapper. Is there any possibility of adding true React support via AST, along the lines of https://github.com/rexxars/react-markdown ?

That is the "correct" approach. React does DOM diffs, so with ASTs it will only render the changed parts instead of re-rendering everything like right now this repo does, which brings perf and other improvements.
