(Bug 5073) Don't use width:100% on #content

The #content element is nested and may have applied margins to it that
could cause scrollbars. So let's use nested-collapse instead of the
default.
(Bug 5073) Remove redundant _skin-colors include

Already included in tropo-base
(Bug 5073) Adds an error section to the top of Foundation pages
(Bug 5073) Add a 1em left margin to all lists
(Bug 5073) Add .row .columns container around page content

This is needed for all pages (to add space around the edge), so add it
to all pages.

Individual pages can still have their own per-section row/column
wrapper.
(Bug 5073) Initial load of pages should have no-js class

Use it to hide elements that require JS to work (class will be changed
after page has loaded)
