Implement treeview to visualize class member variables that are images

Thanks, I think this will be very helpful.

I have typically some objects with have several images as members. I added some giwtypes to display one of them. Displaying all of them is not possible I believe, since the backend only checks if the parent was already processed, which is the case after the first member was found. I thought about changing the backend such, that all variables are parsed down to all members and then only add giwtypes for the basic types. But I think that would require substantial changes, probably treeview instead of list and some mechanism would be required to avoid endless loops if a variable has a pointer to itself or its parent. At that time I had no idea how to debug it and created this issue. At the moment I have no time xD. I hope I will have some time in the future to look into it.
