GUI: Fix "clear" buttons after theme switch (bug #3482459)

Browse source 
Because the "clear" buttons are very different between themes (in
the Modern theme they have a graphical symbol, while in the Classic
theme they have a letter), they have to be removed and re-added
when reflowing the layout. This is patterned after how the
LauncherDialog class handles the larger changes in layout.

Removing widgets from a tab turned out to be trickier than I first
thought, so I had to move the removeWidget() method from Dialog to
GuiObject.
