Create model and column in wxDataViewTreeCtrl::Create(), not ctor.

Browse Source 
Old code created the tree model and its unique built-in column only in
wxDataViewTreeCtrl ctor but not in Create(), meaning that the behaviour was
very different depending on whether you used base class ctor call or Create()
in a derived class. This was confusing and completely inconsistent with wx API
in which using the default ctor and Create() is supposed to always have
exactly the same effect as using non-default ctor so change this to create the
model in Create() so that it's always done.

Slightly update the documentation and also add wxDataViewTreeCtrl::Init() for
consistency.
