Member DB styles, update list view, #main padding

- Added some member db styles for grid view.
- Fixed the problem where the map-opened and filters-opened classes
were merging causing neither to work.
- Threw map bubbles in member list view into a div.
- Added foundation columns onto main#main.site-main and a row
around it to help fix the padding problems (also removed padding
set for this element in the minified stylesheet.
