Support for running the testsuite in command line programs for continuous integration.

Here is a small example inspired from SDLmain.c:

g_launcher = new JGameLauncher();
InitGame();
MTGCollection()->loadFolder("sets/primitives/");
MTGCollection()->loadFolder("sets/", "_cards.dat");
options.reloadProfile();
TestSuite testSuite("test/_tests.txt");
int result = testSuite.run();
DestroyGame();
delete g_launcher;
return result;
