* Applied a patch from Luiz Americo which fixes some alignment issues inside TfpgPanel.

* I implemented more alignment fixes for TfpgGroupBox and TfpgBevel.
* I improved the painting of the focus rectangle it TfpgCheckBox and TfpgRadioButton.
* UI Designer's Unknown widget can now act like a container component.
