Liquify site header and main page telephone image

Taken in isolation, this causes some awkwardness when resizing your
browser window to very skinny, and the mobile benefit won't be realized
until some more fixed-width boxes are slain, but it's the first step.
Liquify the .solutions.container

Working top-down on liquifying the main page, this div is next.

This makes the "Get started" bar with mobile icons into a fluid
container. Still not too much effect on mobile due to remaining fixed
width elements forcing the layout to expand.
Liquify 'Need some privacy'

This makes article#privacy fluid.
work on encrypted voice / carousels
encrypted texts section looks alright at certain zoom levels
Enforce max width and auto margins on containers to make the front page look good on large screens
Adjust whitespace allocation on carousels
Avoid fixed height on the article tags... they dont scale well. Use clearfix properly instead
Make raven logo/flag scale with screen size
Clean up carousels for small screens

In mobile-first best practice, style carousels to be front and center on
small screens, floating to the left or right on wide screens only.
Minimize carousel padding to unbreak layout on narrow screens
Make blog look good on all screens

Remove the fixed widths and margins.

Includes some tweaks to the header to make it work well with
the blog arrow element.
