2020-11-09	Adress most of the second round of Angelaccio's review comments	Felix Ernst
	This commit applies most suggestions which were made on the MR. Most notably the DolphinUrlNavigator class is split up which leads to the creation of a DolphinUrlNavigatorsController class. Additionally some minor coding style and const correctness changes are included. The error value of cached integers is changed from -1 to INT_MIN because situations could come up in which -1 would be a valid value.

2020-11-09	Make UrlNavigators in the toolbar the only option	Felix Ernst
	The UrlNavigators will be automatically added to the toolbar. The Sort By action is removed from the default toolbar to make space. Remove all options to have UrlNavigators outside the toolbar and remove those code paths. Make it so the new NavigatorsWidgetAction contains two UrlNavigators when in split view mode. Spacing was also added to align these UrlNavigators with the ViewContainers when enough space is available. Force the toolbar to be either at the top or bottom of the window. Set a sane sizeHint for DolphinUrlNavigator. It would be better to do this in KUrlNavigator in the future. This commit also contains a changes which should be moved to a separate merge requests before this gets merged: - Add an expansion animation when split view is enabled by the user
