Implemented new Stops API link, works well.
Bus API implemented again, since we will have buses tracked on the next version release.
Bus refresh implemented. Refreshes every 5 seconds. Could make it less, but right now 5 seconds seeems good.
Streamlined service code. There were some methods that were repeated code with one tweak, so I made it such that every call can use one method. Also, I revised some methods so that they meet iOS method standards.
Got map to dynamically scale the center and zoom parameters for the MapView, but I think I need to modify how the center is calculated...
Zooming works now, scales perfectly.
Took out landscape support, decided to go with an all portrait window app. Also took out the landscape support for our sidebar view controller since we're no longer using it.
Merge pull request #7 from greggjs/greggjs

Added new API links, fixed zoom and center issues for routes, removed landscape mode support.
