Don't force users to inherit from QDeclarativeDesignView. Instead we're
using now event filters to let a user attach a QDeclarativeViewObserver
object to a QDeclarativeDesignView.
- Removed the "cpp/" dir
- Moved main.cpp and symbianicon.svg next to the main .pro.
This also reduces the dir depth in the project view.
- Introduced "qmlapplicationviewer/" dir, which will contain the files
which the user should not modify. All the files there have the base
name "qmlapplicationviewer"
- Moved/renamed "qmlapplication.pri" to
"qmlapplicationviewer/qmlapplicationviewer.pri"
