Fixed for widget and Rss feeds

-The rss feeds were fairly simple to fix, I had forgotten to change a method call in MainScreenSocialView when I changed a method name in RSS_URL enum.
-The widget crash seemed to be caused by an IndexOutOfBoundsException, in WidgetService's getViewAt(int index) method, I added a check to make sure that this won't happen. The index value passed to the getViewAt() method is something that is handled by android so I just had to work around it. I found this forum post to someone that was having the same issue and they suggest it might be an android bug https://groups.google.com/forum/#!topic/android-developers/j8H0O8Wb0B8
