Rebalance wands/rods/staffs

[takkaria]

For wands, need more guidance from people who get deeper than me. :)

Todo:

• Consider stealing (and rebalancing) some of the powerful/rare chargeables from OAngband.
• Remove staff of CLW
• Merge Rods of DetTreasure? + DetObjects?, extend over whole level
• Rods should generally be rarer and deeper. (all should start at dlev8)

• Remove _DetTreasure, _DetObj, _DetDoor/Stair, replace with rods of the same.

As much as I absolutely love them, I have to say that Rods of Fire Bolt are overpowered. Available at stat gain, dealing 16d8 damage (my level 30+ mage was doing only 12d8 with Fire Bolt) or 72 average damage, get yourself a nice stack of them and you can pretty much zap continuously. Anything not fire immune dies really fast, and keep in mind it has 20% chance of a beam.

Nevermind. Ignore what I just wrote. I didn't see that this was opened months ago, and I see that the object file has been edited. I was commenting on 3.0.9.

It's still valid, since I've not changed the effects of any items.
