Add T to App

[epicstar]

It's officially out. We should upgrade our app to use the v3 API over the v2 API. Advantages:

• T is now on the map
• use of detours (by default, the detours are default on the getpatterns GET method... but there is a new API that takes more advantage of the detour API)

There are some breaking changes... For example, we cannot get patterns unless we specify what agency the route comes from.

First part done by adding logic to the Date class for keeping track of "day" and "quarter" with extensive unit tests. Next step is to get the route list to dynamically load from the information either on disk or through the internet depending on the Date.afterQuarter() rule.
