GXemul Code2

(same as in previous versions of GXemul).
Implementing CommandInterpreter::RunCommand, so that commands
can be executed. "help", "quit", and "version" work
interactively now :)
20080103 CTRL-A/E (for start/end of line) and CTRL-B/F (for back/
forward cursor movement) now work in the console UI.
Mapping ANSI/VTxxx/xterm cursor keys (escape + [ + misc) to
CTRL-A/E/B/F/N/P.
Adding command history support to the CommandInterpreter.
Classes that perform unit tests using the UNITTESTS(classname)
macro are now tested (almost) automagically by
UnitTest::RunTests(). (.h files must still be included.)
20080104 Connecting cursor up/down keys to the command history.
Adding Component::Clone. (Not really used yet.)
Adding CTRL-D support to the command interpreter (remove
character to the right).
Actions will now be placed in src/main/actions/.
Implementing an AddComponentAction.
20080105 Beginning on TAB completion in the CommandInterpreter.
Implementing the UndoCommand and the RedoCommand.
Adding CTRL-K (kill end of line) to the command interpreter.
Implementing RemoveComponentAction.
