Allow customization of ResolverActivity via RRO

* Add DismissableView to somewhat decouple ResolverActivity and ResolverDrawerLayout
* Add config_resolverActivityFilterLastUsed so filterLastUsed (and in turn layout with default) can be disabled.
* Add null checks and instanceof checks in ResolverActivity to break the assumption that the root container is always ResolverDrawerLayout
* Replace swiping up on contentPanel with swiping up in title_container. This is necessary to prevent a dialog container being dismissed.
