Minor Header CSS & A crappy way to position footer

I'm flabbergasted that both #modx-content and #modx-leftbar are
position:absolute. It completely does away with making any use of the
box model. I almost had everything laid out without either being
absolute, and using floats, but them needing to both be 100% doesn't
allow for anything to go under (especially with body overflow:hidden)
so I came up with this for the footer for now which I don't love
Cleaning up Search Results

Although I think this may be better as one column...
One Column Search Results

I still feel like it might be better to add a Search box to the Element
Tree, not have a search at all in the header and keep it tucked away
under a menu item. Point being don't think it makes much sense to have
two search boxes on the page at once, so another option would be if
this header search works well…nuke the ones in the tree altogether
