* Add screen-mobile.css with basic mobile styles
* Force loading of screen-desktop on IE8- due to lack of
@media width support
* Add some new divs and a set of spoof cactions for jumping
around the page (what's js?)
* Replace cactions label with a more descriptive string (was
previously set to display:none regardless)
* Also add a set of icons for fixed widths for tabs and things
(icons-source.svg is the source file for the set, and includes
a few others that ultimately weren't used here)
Cutoff 850px. Desktop styles should remain unchanged, with
mobile remaining stylistically consistent.

Also delete unused images, since even if something is
somewhere using them anyway (looked, couldn't find
anything), it wouldn't be able to find them in the new
image location regardless.
Wiki.png, magnify, and link are all part of core and have
been for some time.
