Incinerate lowercase elements

[sfcgeorge]

I am extremely in favour of incinerating the lowercase element methods. I've already had two name collisions; the p method and defining my own small method. There are too many html elements with names you would likely call a method. Plus the all caps DIV style looks clearer, and harkens back to the early days of HTML tags being all caps which is nice in a nerdy way.

Moreover there are for some reason 3 ways to write HTML elements: div {} or Div {} or DIV {}. We should get rid of the middle camelcase one too. Leaving only DIV {}.

I bet this would simplify Hyperloop code.
