Subject: [PATCH] Offer to mkpath when user goes to a nonexistent folder

This commit changes Dolphin's behavior when a nonexistent local path is
entered into the location bar. Previously, an error message would pop
up. This commit adds a button to that message that allows to create the
path and navigate to it.
