Qt: Convert the list management icons to templates.

Move the rest of the list management icons (remove, copy, clear, up, and
down) to the stock_icons directory. Convert them to templates by adding
".template" to their name.

Switch the UAT dialog to the "new" icons.

Convert the image README to .adoc.

To do:
- Make sure the icons are actually black.
- Convert the rest of the preference dialogs and other consumers.
