Bugs fixed

----------

* valkyries and Barbarians were unable to read the Book of the Dead. Oops.

* fixed specific warning from some artifacts

* the "it doesn't seem to harm" message appears only if the creature is seen

* wishing for an artifact could cause a crash later on. Urp...

* added damage amount display to explosions

* fixed bugs with explosion damage: polymorphed players and invulnerability

  wasn't working right with fireballs, gas spores, etc.

* changed // comments to /* */ to help other platforms out... :)

* also put lots of the Watcom stuff in #ifdefs

* fixed reflection message... again....

* fixed conflict & god-given pets

* fixed "You return to human form" for Gnomes

* crash bug with archeologists falling in trapdoors fixed.

* added message when necromancers gain gain undead warning



Adjustments

-----------

* id wands of healing if you zap yourself

* healing/extra-healing potions give you more permanent hit points

* weapons can be enchanted from +5 now (was +3)

* removed the "steps reluctantly" message from god-given pets... it was

  annoying and misleading

* angels don't show up unless you're in deep trouble.



Additions

---------

* weapon swap command - 'x' -- list spells is now 'X'

* added dark elven equipment -- chaotic elves are now dark elves

* invisible objects (invisible weapons get a +3 to hit monsters who can't

  see invisible; nymphs, etc. won't steal invisible objects they can't see;

  1 in 1250 random objects are now invisible)

* made a makefile for Watcom

* added/enhanced some wizard mode commands

* put in four Neutral weapons from Nehwon: Graywand, Heartseeker, Scalpel,

  and Cat's Claw.



Many people have given lots of helpful suggestions, but several have

been especially helpful and have sent me huge lists of bugs.

They are Wolfe, David Robertson, and Kentaro Shirakata.



Thanks to everyone for their help in squashing bugs. No one likes to

lose a character to a bug, and the more bugs that are found, the fewer

remain.
