Added DOCTYPES to force IE9 into standards mode. In SM IE9 knows about addEventListener. However, adding DOCTYPE regressed rendering in code and blockfactory. This is because in SM, browsers treat table height differently. To fix I added height styles to html and body forcing them to take 100% of the window. Also in this patch the sourcing of common.js has moved from the body to the head (turtle) to fix issue in IE9 and conform with other apps.
