Wt

When using a proxy model, dragging and dropping of items in between others (e.g. to move items inside a model) would have called the WAbstractItemModel implementation instead of correctly forwarding the call to the source model.

I created a PR on github (https://github.com/emweb/wt/pull/233) to fix this. The issue is present in wt 4.10 through 4.12, at least.
