Subject: ManaCost fix

if you have ever noticed that when you cast a Cleric spell as a Magic_user
you get the mana_max - mana_min well the following will correct that error

There are 2 files that need to be edited they are spell_parser.c and spells.h
if you have any problems at all contact me at Aenarion@finality.drachen.com

-- Discliamer if you use this following fix I am not responsible for any
   damage it causes your mud it works on mine which is bpl11 if you have
   any changes that you have added please e-mail me at the above address
   with the changes.

now in the
The following is an example of what is needed

  spello(SPELL_ARMOR, 50, 5, 11, POS_FIGHTING,
        TAR_CHAR_ROOM, FALSE, MAG_AFFECTS);

add the class of the spell if its assigned to mages and clerics use
the lowest defined class level. For the change just add the class
define EX. CLASS_MAGIC_USER or CLASS_CLERIC at the end.

:: example ::
  spello(SPELL_ARMOR, 50, 5, 11, POS_FIGHTING,
        TAR_CHAR_ROOM, FALSE, MAG_AFFECTS, CLASS_CLERIC);

Just add the class of the spell to the end and the mana cost will be correct
