port majority of code to qt5.5+ - a few issues to work out still, and editor changes not done yet - for communication between webengine and python code, we set window .location to 'http://anki/<something>' - the leading http is necessary for qt to call the link handler, which was introduced in qt5.5 - the designer files now use a promoted qobject to create instances of AnkiWebView - we use the css zoom property to alter webengine font size based on system dpi - prefs and addons folder stored in new location (at least for now)

use callback when closing windows remove the old forceClose hack in favour of a callback when closing, so all windows have a chance to save properly before the collection is unloaded also: - fix a warning shown when opening about screen - require a call to editor.cleanup() when closing a window, to make sure any pending js callbacks don't try to fire on a deleted object - make sure we gc webview when closing editcurrent - main.py still needs refactoring to make use of the change
