MD in file export

[andrewxhill]

Following on @clhenrick's comment, it actually would have been really handy if we had made this part a bit more functional,

<script>window.ODYSSEY_MD = "```\n-title: \"Andrew's life story\"\n-author: \"Andrew\"\n-baseurl: \"http://{s}.api.cartocdn.com/base-antique/{z}/{x}/{y}.png\"\n```\n\n#slide1\nsome text\n\n#slide2\nmore text"</script>

we've unnecessarily muddled the MD inside the HTML. What is awesome is that the template uses the MD, so once you get the hang of it, you could drop new md into your html file without the editor at all. So I would propose something more like this,

<script type="text/html" id="sql_template">
'''
-title: "Andrew's life story"
-author: "Andrew"
'''

#slide1

some text

#slide2

more text
</script>
<script>window.ODYSSEY_MD = $('#markdown').html();</script>

@matallo @javisantana makes sense right?

[andrewxhill]

it preserves the human readability of the whole md part
