Conditionally show "reset" button in mobile toolbar

The "reset" button in getMobileWritableItems is now only included if READ_AND_CONFIRM is falsy. This prevents the button from appearing when READ_AND_CONFIRM is true. The same conditional logic was applied to the minified ui.min.js. Code was also refactored for clarity.
