Adding controls to existing menus and getting items prices from traders

[Baertram]

Try to add

## OptionalDepensOn: AwesomeGuildStore ArkadiusTradeTools

to your manifest txt file so the 2 addons are loaded before yours and thus your hook into the setupCallback also contains there hooks already.
Maybe for AwesomeGuildStore needs some more things to check like sirinsidiator already wrote and showed you the function which says "all ready" before.
