[svn r42] Disabled the extensive logging by default. Use the -vv flag to get it back. Fiddled a bit the the testing system. Added a very simple SDL graphics demo.

module condexp;

int f()
{
    return 42;
}

void main()
{
    int i = f() < 25 ? -1 : 1;
    /*int j = f() > 25 ? 1 : -1;
    assert(i);
    assert(!j);*/
}
