Bigger update, took me a little longer than expected.

• The mod now sees the durability level of tools. It won't let you swap a worn out tool for a new one.
• You can now add self-refilling chests!
• Reload config command.
• Separate prices for each store. Prices are now saved in prices.xml and unfortunately your old prices won't be copied.
• You can now have prices with decimals!

aaaand...

• A lot of small bug fixes and changes in the code.
