Add 17 fake objects to objects[], one for each object class. All
specific color as gray. They're grouped at the start--actually near
the start since "strange object" is still objects[0]--rather than
being among the objects for each class. init_object() knows to start
at [MAXOCLASSES] instead of [0]; other code that loops through every
object might need adjusting.
For potions, non-stone gems, and non-novel/non-Book_of_the_Dead
spellbooks that don't have obj->dknown set, display the corresponding
generic object rather the object itself. Fixes the longstanding bug
of seeing color for not-yet-seen objects whose primary distinguishing
characteristic is their color. Walking next to a generic object
while able to see its spot will set dknown and redraw as specific.
It's slightly disconcerting to have objects change as you reach them;
I hope it's just a matter of becoming used to that. (If there is any
code still changing the hero's location manually instead of using
u_on_newpos(), it should be changed to use that routine.)
Most of the new tiles are just a big rendering of punctuation
characters. The potion, gem, and spellbook ones could be cloned from
a specific object in their class and then have the color removed. I
started out that way but wasn't happy with the result. I'm not
artisticly inclined; hopefully someone else will do better. Each of
them is preceded by a comment beginning with "#_"; the underscore
isn't required, just being used to make the comments stand out a bit.
