Added new 'RxBuff' class as a front-end input buffer for the 'Rx' engine. Characters can be written to the RxBuff, and RxBuff will call Rx::Go() automatically when it detects the end-of-command character, and clear the buffer, ready for more input. Added unit test file for this feature (test/RxBuff.cpp). Also fixed recent dates in the README changelog. Started using new naming scheme (dropping the Clide from the start of the filename). Modified Makefile for automatic dependency generation for 'test/' folder.
