This patch was intended for a stock Circlemud patch level 12

What does this patch do?
-=-=-=-=-=-=-=-=-=-=-=-=-
It will:
  1) Implement player races.
     Human, Troll, Elf, Gnome, Half-Dragon, Minotaur
  2) Implement race unique body parts
  3) Add a few body parts:
     Ears, Wings, Tail
  4) Allow you to have unique races like Dragon, Centaur, and
     even Thri-Kreen, each with different body parts...
  5) You can now tell where to wear eq...ie: wear eq wristr, wear eq wristl
  6) You can have spells that 'activate' body parts..such as
     tentacles..

How to install this patch.
-=-=-=-=-=-=-=-=-=-=-=-=-=-
1) Place the racebody.diff file into your src directory
2) Run patch < racebody.diff
3) Update your makefile (I believe you run configure)
4) Recompile

This patch was tested on _stock_ CircleMud bp12 with no errors.  You may have
to patch by hand if you have made modifications to your code.  It will 
corrupt the player file.

Adding races/body parts
-=-=-=-=-=-=-=-=-=-=-=-=-
Adding races:
  A) stucts.h
     1) add the race define, ie: #define RACE_DROW  7
	 2) umpdate the NUM_RACES to the number of races
  B) race.c
     1) add the race abbreviation to race_abbrevs[] array
	 2) add the race name to the pc_race_types[] array
	 3) add the race to the race_menu[] variable..
	 4) add another line to the race_data struct in this format:
	    {RACE_XXX, BODY_XXX|BODY_XXX}
	 5) add another case to the parse_race() and get_race_bitvector()
	    functions(the letters used as the case in parse_race() should
		be unique for each race, and should match the letter in brackets
		in the race_menu[])
  C) recompile

Adding body parts:
  A) structs.h
     1) add the WEAR_XXX define, ie: #define WEAR_WIELD     16
	 2) update the NUM_WEARS define
	 3) add the BODY_XXX define(it should be the same number as the
	    WEAR_XXX define), ie: #define BODY_WIELD     (1 << 16)
  B) constants.c
	 1) update the where[] and body[] array
  C) race.c
     1) add the new BODY_XXX to the appropriate race separated by the | operator
  D) act.item.c
     1) add another check in find_eq_pos() in the following format
	    if (CAN_WEAR(obj, ITEM_WEAR_WINGS))       where = WEAR_WINGS;
	 2) add the new ITEM_WEAR_XXX to the end of the wear_bitvectors[] variable
	    in the perform_wear() function
	 3) add the message to the end of the already_wearing[] variable
	    in the perform_wear() function
	 4) add the correct set of messages to the end of the wear_messages[] variable in
	    the wear_message() function
  D) recompile

Making spells that affect race or body parts
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
Poly spells...
	Just make a spell that adds AFF_POLY, or AFF_DRAGON, however you prefer
and hae it call the set_race(ch, race) funtion to change the race and body
parts.  The trick is to have it change back when it wears off.  You might
want to add a orig_race variable to player data so you know what to revert to.
I didnt add this because it wasn't necessary for the race funtionality...

Body part spell
    First the intended body part must be installed.  Then make a spell that
adds the affect and does a SET_BIT(GET_BODY(ch), BODY_XXX).  That will 'activate'
that body part.  Then when the spell wears off, do a REMOVE_BIT(GET_BODY(ch), BODY_XXX)
to remove the body part..
