Integrating QProxyStyle

This class adds convenient support for proxy styles in Qt.
Note that to support proper proxying, styles now
call their functions through proxy() so that the proxy regains control
over subcomponents. Note that there is a small price to be payed
by the extra function call which can at the cost of readability
be redirected to the private class member in the future.
