[INTERPRETER]
* NEW: Remove the now useless testing specific code.
* NEW: 'gbx3 -T' now just loads the 'gb.test' component and calls Test.Main() passing it the '-T' option argument.
[GB.TEST]
* NEW: Move 'gb.test' sources in '/main/lib'.
* NEW: 'gb.test' has now a part written in C that allows him to load project classes on demand.
