Allow the user to sort the control contents by clicking on the columns with
wxCOL_SORTABLE flag and also provide SetSortColumn() method to sort the
control programmatically.
Also add wxTreeListItemComparator class and SetItemComparator() method to
allow customizing the way the items are compared.
Update the sample to show how to define a custom comparator.

Override wxDataViewModel::IsListModel() to return true if wxTreeListCtrl
doesn't have any depth. This results in better display when using the generic
implementation of wxDataViewCtrl as no space is reserved for the (unnecessary)
expanders in this case.

This is a facade for wxDataViewCtrl allowing to easily work with multi-column
trees, possibly with an optional checkbox in the first column. Its API is very
similar to wxTreeListCtrl and it provides a simple migration path from the
latter.
Add the class itself, documentation for it and minimal unit tests.
