[Development] syncqt generated forward include headers

[Denis Dzyubenko]

Hi,

I've made a patch for syncqt to make it generate forward include
header (e.g. "include/QtCore/QObject" and "include/QtCore/qobject.h")
even if the class name doesn't have a "Q" prefix - in qtjsondb module
all classes have "JsonDb" prefix instead and that confused syncqt.

I made it configurable via sync.profile - http://codereview.qt-project.org/12128
