Compare store items to the items that are equipped

[GoogleCodeExporter]

Buying things would be much easier if I could easily compare the equipped item 
with the one in the store.

This would be applicable to both items that are equipped and items in the 
player's inventory.

And added to this, if there isn't an ideal market system in place where with 
supply and demand prices could vary from town to town then just eliminate 
weapons and armor from the list of available products to purchase as there is 
no added benefit to purchasing something you already own(yes, my fat fingers 
have made some mistake purchases).

IMO you may need 2 rings giving 2x6 additional attack damage. ;-)

Perhaps if I buy stuff to equip, there could be a window:
Should this item be bought? (with infos about similar items in the inventory)

At least the weaker items should be eliminated. (except for rings). How you 
decide what is weaker, though, is a good question.
- Most defensive stuffs have one stat: block. easy. Once you have gloves 6%, 
don't show anything weaker than that. (but show e.g. block -9 attack +17)
- Shields have attack penalty and block benefit. Again, easy.
- Weapons are more complicated though. All have AP, attack and damage 
(min-max). Those that are same or worse in all four aspects (same or higher AP, 
same or lower attack, same or lower min AND! max damage) can be eliminated. 
E.g. once you've got iron sword, most of the weapons should be eliminated. The 
problem is, as soon as you have the venomous dagger (damage 1-2), most weapons 
are back...

Once item properties replace the current item scheme then it will become too 
complex to define such exclude rules, especially outside the property group. 
(suggested in issue 38)

Example: Deadly steel sword of speed
base dmg: 2-5
+ 1-3dmg (deadly)
+ 5% AC (deadly)
+ 10% AC (speed)

Comparing this against plain steel sword is no problem, but against other 
properties that give other modifiers like crit is.

So you got my point :)

I'm against exclude rules. Assume someone wants to buy a very good sword. 
Therefore he has to sell his expensive armor to afford it. So he wants to know 
what cheaper armor is available, without having to uneqiup or sell the 
expensive armor.

The other downside is that exclusion rules should be very complex.
