Trying to fix commit errors
fixes issue #6. removed some unused code
Update index.html
Update content regions

Content regions now hold a button interface for adding/arranging/viewing
content items within them instead of a click and drag mechanism. Still
have a lot of JS work to do here to adjust for this new treatment of
regions.
update content regions, remove south and southeast drag handles, add hover css, remove autogrow closes issue #15
add child count to content region
implement modal window for region editing

On to plan D for content regions!
