Handle desktop (>768px wide)  size iframe resizing for LSL

Mainly:
Got the LSL iFrame working pretty well in Firefox and Chrome

New behaviors:
Sticky footer pushes the page down on all pages except LSL
LSL iFrame scrolls rather than page, footer always visible

Also:
Removed the div #bodycontainer for less nesting
Added a min and max container resize button

Can you suggest a better way to size the .iframer-wrapper and handle the window resize?
