John Diamond c1063e3219 LibGUI: Disable Open/Save button in FilePicker when nothing is selected ...

The existing behaviour is that filename_textbox is cleared if a node of
the wrong type is selected. Here we reflect that state update in the
state of the ok_button.

This change helps the user to avoid confirming (and seeing an alert) if
they press "Open" after clicking on an invalid node.
