- vias were always left selected, include vias in tracks filter - as in legacy
- make text filtering work
- cleanup drawings filtering code
- hide checkbox "Include items on invisible layers" because it does not work in GAL
This means the dialog can be accessed from both GAL and legacy modes.
This also removes the use of static bools for passing the selection
states and instead used a struct of values passed in by the calling
code.
