Add RootController

This controller is now the target for `root_url`. It sub-classes
DashboardController so we can render the old default without a redirect
if the user hasn't customized their dashboard location.

+# RootController
+#
+# This controller exists solely to handle requests to `root_url`. When a user is
+# logged in and has customized their `dashboard` setting, they will be
+# redirected to their preferred location.
+#
+# For users who haven't customized the setting, we simply delegate to
+# `DashboardController#show`, which is the default.
