Under GTK the columns of wxDataViewCtrl (and hence wxTreeListCtrl) are always
resized to cover the entire control width. For consistency, also do it under
the other platforms and give the remaining space to the first column and not
to the last one as GTK does by default, as the first column is more important.
Do this even if this results in reducing the size of the column: presumably,
if the entire control itself can be resized, the user wouldn't bother resizing
the columns and, on the contrary, if the user did resize the columns, the
entire control size is unlikely to change, so in practice we don't risk
overriding the user preferences and reducing as well as increasing the first
column width works much better by default as it doesn't leave the other
columns invisible after making the control wider and than reverting it back to
its initial, more narrow, state again.

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.

It can be useful to have access to the window used to actually show the items
by wxTreeListCtrl, provide two accessors for m_view: a wxDataViewCtrl-specific
one and a generic one returning just a wxWindow that can be used to keep the
code isolated from wxDataViewCtrl.

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.
