Update Normalize
Update quotation style
Sliding doors is code snippet, not reset
Update clearfix

There was an error in content display when tables didn’t have `border-collapse:separate;`.
This explicitly sets that property and value regardless of full reset, just to be sure.

Future-proof `viewport`
`no-repeat` is not needed
Initial scale of page should be reset
Modernizr and H5BP server-configs as additions
