Long options are now supported in the command-line interface (now used getopt_long). Various code to Option class and RX decoding has been added/changed to support this. Added Clide-Global.h. Deleted internal dependency section in README (not useful). Added mention of POSIX.2 standard in README. Fixed unit test that was failing (strcpy() was being passed a NULL). Added new Makefile option clean-ut, which just cleans the unit test code. Added unit tests for long options.
