Mostly mobile monkeying

Mostly poked at mobile today switched it from an iframe to loading into a div, fixing some of our scroll & click through issues and fixing it for Android 4.

Experimented with iscroll 4 library to handle the scrolling and add zoom, but too slow for now.

A little more poking at EmbedScript experiment; I have a sandbox domain temporarily on a Wikimedia Labs VM. Will show off more on this later.
