LibGUI+PaintBrush: Fix to GFilePicker and PaintBrush enhancements.

GFilePicker
- Fixed GFilePicker to use new ref-counted construct method to stop crashing on open dialog.
  - PaintBrush is still crashing on open dialog due to an unrelated issue.

PaintBrush
- Created 16x16 icon for PaintBrush
- Moved Open option into App menu.
- Changed help menu to make use of the standardized About dialog.
