- Add and use new icons
- Make some labels more explicit
- Properly document copyright of both the new icons, and the icons used to make them
- Note that the Cartoon icons fall under the same copyright as all other Cartoon icons, so no licenses.txt update is needed
Anything not provided or defined by a skin will be used from the defined base skin, if specified.
For example, if a skin provides a base_theme of "cartoon", any icons/buttons/etc. not provided by the skin will be pulled from "cartoon".
