New Standard Variables: Doh!

[neocotic]

How have I not thought of adding these before:

• html - HTML of the entire page
• markdown - Entire page in Markdown
• text - Text of the entire page

Obviously, these will only work in non-protected (i.e. non-chrome) pages but this would be very useful I imagine. Especially when coupled with the new wordCount operation that's being added in #193.

This'll probably be best implemented by only fetching the HTML from the content script and deriving the rest on-demand.

I can't decide what the scope of html should be (i.e. the entire page source or just that of the body element). My current thinking is that html should be the entire page source but text and markdown should only apply to the contents of the body element ( unless it doesn't exist? ). For example;

# content.coffee
html: document.documentElement.outerHTML

# background.coffee
markdown: ->
  markdown = ''

  if @html
    container = document.createElement 'html'
    container.innerHTML = @html
    $container = $ container

    $body = $container.find 'body'
    markdown = md if $body.length then $body.html() else $container.html()

  markdown

text: ->
  text = ''

  if @html
    container = document.createElement 'html'
    container.innerHTML = @html
    $container = $ container

    $body = $container.find 'body'
    text = if $body.length then $body.text() else $container.text()

  text
