Add Starred Routes list (#354)

[millanp]

I added a new tab below Starred Stops called Starred Routes.

It takes you to a list of routes which are starred at at least one stop.

A long press on a route shows a popup menu with various options, including an option to remove all stars from that route.

There is also a button in the top right menu to remove all stars from all routes.

When the user taps one of the starred routes, it shows the map view for that route.

This is better than the old method of showing a text-based list of stops because the map is much more readable and it provides useful information about the actual location of buses. Most users I have spoken to do not know that the route-specific map view exists, and they say that it is useful when I show it to them. I modified the "recent routes" list to have similar behavior.

I made one change to existing code, factoring out the classes RouteInfoLoader and RouteInfoLoaderCallback from RouteInfoListFragment into QueryUtils. This is because I need to load the long name of a route when it is starred by the user, to make sure that the Starred Routes page is fully populated.
