Memory corruption

[vchekan]

My application started exiting with status code 1 and I think one time I've seen signal 11 too.
Investigation narrowed it down to this line:

 let mut local = $wrapper{
    origin: Box::new(origin),
    ptr: ::std::mem::uninitialized(),

I've replaced uninitialized() with zeroed() and my app is working again:
vchekan@21f25e6

I do not understand qml low level api and I am not sure what is going on with pointer manipulations in $wrapper::with_no_props() and QmlObject::new() so i do not consider it a proper fix, so if somebody has insight, please share.
