november 2019 updates

Updates :

• chocolate heretic : v3.0.1 to v3.1.0 (now 64-bit only!)
• IWAD : "official" v0.18 to Catoptromancy's fork 007 (better graphics...)
• chocolate heretic is launched with the adequate emulated version (1.2 or 1.3 depending on the WAD)

But anyways, this is still experimental and bugs are to be expected (especially with random WADs).
