Gold Drops, Item Gold (Sell Value), Item Upgrade Balance

[davidjreese]

General concerns I have about the balance now that we have all the game systems in. Will be keeping an eye on

• [ ] Do we need to up the amount of gold (and frequency that monsters drop it)
• [ ] Do we need to increase the sell value of items a bit (will also impact how difficult it is to power infused gems)
• [ ] Do we need to make any other adjustments around item upgrades/treasure drops now that things are more balanced
• [ ] Add more details/books/info on the 'item slot' of a schematic not mattering except for basic armor/weapon type and look of item (stats are no carried forward).
