Add support for defining properties from member variables.
This associates properties with member variables and
avoids writing getter and setter methods manually.
The metaCall() method directly accesses the member variable,
so additional method calls can be avoided.
The metaCall() setter code also supports NOTIFY signals,
which means the according signal is emitted when the property
gets written.
