COX 2 Ver. 0.87.20 release

Sorry for the infrequency of updates of late.  I've been injured in such a way that computer use has become more difficult, and am still some ways out from being able to code for prolonged periods again.  When I can, rest assured, I will!

In the meantime, a couple of Caverns II gamers have uploaded their playthroughs!  In addition to finding this inordinately entertaining, I spotted several bugs in their games, and couldn't resist tackling some of these, and instituting some quick new ideas I had while watching their stuff, too.  Huge thanks to Dynast11 and cryptrat for the playthroughs, as well as Combatereak for calling my attention to them.  If anyone else has an urge to record their gameplay, I do find it very instructive, so just let me know in the comments section!

You can see their stuff here, by the way:

Thanks again, and here's what's new:

Minor Improvements:

- Made Absorb Life Energy spell and Drain Life spell completely ineffective against Undead, both for thematic purposes, and because the spells were slightly overpowered. Also made monster spellcasters not cast these spells against undead monsters.

- Made all monsters MUCH more hesitant to enter dangerous squares.

- Made monster intelligence further affect how likely monsters are to enter dangerous squares, with Animal and lower level intelligence monsters being more likely than normal intelligence monsters, and Genius level monsters being less likely.

- Made how nauseous a monster is affect its hesitancy to enter Stench squares - e.g. monsters who are already nauseous for 30 turns will not hesitate, and those are nauseous for only 1 remaining turn will still be quite hesitant, but not quite as hesitant if they weren’t nauseous at all.

- Made higher level monsters more hesitant than lower level ones to enter Ice squares, since they’re more likely to break through.

- Monster level no longer affects likelihood of a monster to enter dangerous squares that affect monsters of all levels similarly.

- Monsters who are Fire Resistant are now more likely to enter Lava, Hot Coals, Fire, Raging Fire or Fumaroles, with the increase in likelihood based on how high their Fire Resistance is.

- Monsters who are Acid Resistant are now more likely to enter Acid and Acid Vapour, with the increase in likelihood based on how high their Acid Resistance is.

- Monsters who are already poisoned are now more likely to risk entering Poison Gas squares, with the likelihood increase based on the severity of their poison. I.e. Mildly Poisoned monsters will be slightly more willing to risk entering Poison Gas squares, while Grievously Poisoned will be far more likely and Critically Poisoned won’t hesitate, since they have nothing to lose.

Bug Fixes:

- Fixed bug causing Stench Cloud spell to create Fire instead of Stench if you used it to the West.

- Fixed error giving player the option to attack a sleeping monster even if their own character is asleep.

- Fixed error playing sound effect for Basilisk Snare at full volume, regardless of your chosen sound effects volume level.

- Fixed bug that would only assign 1 random resistance to Xaskazien instead of 2.

- Fixed loophole having Scroll Merchants sell Grease spells at a base price of 0 gold pieces.

- Fixed error warning player they’re about to potentially pick up more gold than they can carry, even when they have no option but to pick up the gold (like when succesfully praying at an Alluman Shrine, for instance).

- Fixed error mislabeling Drain Life spell in the spell list.

- Fixed bug that would always crash game when trying to generate a Phantom Lair.

- Fixed bug preventing Raised Drawbridges Over Ice from being graphically displayed in the viewscreen.

I noticed but have not yet been able to track down a bug that sometimes doesn't display water based monsters (fish, etc.) on the Map Screen, if they should be detected by ESP.  I'll work on it!
