These removed styles match no elements in the
Special:Preferences page since the OOUI transformation.
Bug: T208923

Dropdown menus and js interactiveness for people who like to pretend
we live in a modern era or something.
Does not actually support newfangled tapping and swiping stuff.
Does not properly support echo. (will follow up)

No guarantees that these styles actually apply to anything anymore.
But at least the TODO is resolved!

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.
