Merge pull request #3 from jim618/release-4.0.0

Release 4.0.0
Adjusted page header styles, reduced it a little and removed top border. Changed dl panels so they look deactivated before acccepting t and c checkbox. Put dl panels and checkbox into a panel to create a grouping effect.
Reduced header slightly more. Still needs some more adjustments, but may try other sections of page.
Moved dl panel header items side by side to allow for more vertical space.
Adjusted dl panel header for smaller screen sizes, now seems to behave quite well.
Brought features heading up more in line with video.
