Remove div.container and div.row

Instead of using another set of .container and .row in the layout, these have been removed so that they can integrate into layouts where a space has already been made for them. This gives the developer more control over the layout in case they don't need an extra container built in.

This may look like a ton of changes, but it's actually just the removal of `div.container` and `div.row` and un-indenting their child elements.
