Modified Command class to add nullary (no argument) constructor. Began working on implementing code for cmd_loadc(...) and cmd_unloadc(...) for dynamic command loading/reloading. Tweaked AttackCommand to put the player in COMBAT mode after confirming a hit. MUDServer code cleanup, lined up some comments and removed empty space. Added functions: getName(), getServerName(), getVersion() to expose some data about the server. Copied code from parse_pgm into new class, ProgramInterpreter.
