Title: Set proper base style for the custom proxy styles

Make sure the proxy styles of ctkCollapsibleGroupBox and ctkCheckBox
use their parent widget style as the base style (or the QApplication style
if no parent). Currently, no update of the base style if the widget changes
parent as it segfaults, probably due to ownership conflicts. Needs more
investigation.
