full IDisposable implementation (#34)

* full implementation of IDisposable, not stable, lock and still leaking

* override dispose in popper to handle _content not yet in graphic tree (when never shown), test focusedWidget when disposing

* prevent canceling thread multiple times causing a deadlock

* test parent type when trying to close window
