Added a new example 05. UI Fragments.

This example demonstrates the use of RajawaliFragment. The example contains
two Fragments, a ListFragment and a RajawaliFragment. Selecting different
options in the ListFragment rotates a model car into different orientations.

I believe this to be a very useful and powerful layout model.
Moved the new UI Fragments example to the end of the list.

Its only fair :-)
Also fixed the degree symbol (Example 31) which was not displaying correctly.
