Feature Request: Add "deselect_path" to TreeView widget

Currently, TreeView widget has a select_path() method but no public API to de-select, except to clear the whole tree. I propose a new method named deselect_path(). In Qt, it is simply the opposite of select_path(), as follows:

class TreeView(...):

    def select_path(self, path):
        item = self._path_to_item(path)
        item.setSelected(True)

    def deselect_path(self, path):
        item = self._path_to_item(path)
        item.setSelected(False)

I think between the two that you show, I’d prefer reusing select_path. The reason is that it makes the code simpler in cases where you want to calculate selections–you don’t end up having to write conditional branches or use first-class functions to choose a different method. Instead it just changes the state kwarg, which seems more readable to me.

this would actually just deselect the one row out of many?

Yes. I have many rows selected but then I want to only de-select one of them. I use this feature in MosaicAuto plugin in stginga.
