All this bundle does is convert the remaining transitional doctypes to HTML5.

Removes the last examples of .titlebg2 from Elk (Calendar.template.php and Search.template.php)

Adds a skip navigation link to index.template.php (basic a11y addition for keyboard users).

Removes the #outer_container div from GenericControls.template.php (wasn't doing anything useful).

Adds a slight menu tweak to admin.css (which is still a mess otherwise, but ignore that for now).

Fixes dodgey old language strings in Install.english.php (https://github.com/elkarte/Elkarte/issues/584)

Basic cleanup for help pop-up markup and CSS.
NOTE: Since the max-height appeared essential, I put it in script.js
so that people wouldn't remove it and then wonder why things broke.
Other CSS was moved the other way, from script.js out to index.css.
Removed catbg class from the heading, as it will be deprecated, and left it as plain h3.
Also, added title to close link for a11y. @todo - Really should have a proper language string.
