The main window's font-glyph icons were rendered with IconFontSwing.buildIcon,
which bakes a fixed colour into the image (black by default, DARK_GRAY for the
Playlist Editor tab), so the Screen Capture camera, the Playlist Editor tab icon
and the View menu icons ignored the selected theme and were nearly invisible on
dark themes.
Adds ThemedFontIcon, which resolves its colour from UIManager at paint time
(Label.foreground, MenuItem.selectionForeground while a menu item is armed,
Label.disabledForeground when disabled) and re-renders only when the colour
changes, so icons follow theme switches without a restart.
