0.7.1 Release and example code

This is the 0.7.1 release that has been pushed to the market which fixes
a bug in the weather refreshing and makes the weather screen display
relevant loading information.
This also includes the "fragment6" unused example fragment and a small
bit of code in fragment4 and its list adapter that let it run code when
the user reaches the end of the list.
APK size optimization

Removed images to reduce APK size and added code to begin loading a
second page when scrolling to the end of the sports feed list.
Git extra commit
