New build: various small fixes

• Fixed missing par times for Thy Flesh Consumed
• Don't show par times for E1M10 and MAP33
• Fixed incorrect music for E1M10
• If user provides BFG Edition Doom2.wad, use the level names from that ("IDFKA", "Keen") instead of the original names

Thanks ZDoom forum user Yarn366 for spotting these issues.
