Markdown and HTML widgets

[cjbrooks12]

Create out-of-the-box parsers for handling basic HTML and Markdown content, especially for Compose. Other platforms have their own mechanisms for handling such input text, but Compose doesn't have anything natively.

Alternatively, create an out-of-the-box Syntax for HTML or Markdown that can be installed into any parser. Would be nice to have #6 done so that this Syntax can reference the common tags for building itself
