Unified all Java examples to *match* <LIBRARY>[_otherstuf]_Example.java.
Note, a handful of the examples have a pseudo-random string for the
first component (see FlexSensor_Example.java, ideally this would be
Flex_Example.java).
This commit allows for quick development on a single sensor library
since a -DMODULE_LIST=mysensorlib now works with Java examples
(previously Java examples would fail generation when using
MODULE_LIST).
* Renamed examples
* Updated class names
* Updated library descriptor .json files
* Updated sample mapping file
TODO: Make this work like the C/C++ examples - grab the target library
name from the filename and grab all dependencies from that target
library. Fix the handful of example names which don't conform.
