Version 0.7.7

Hey, folks! This update is all about the text.

What changed:

• [Almost] full Greek translation! (Thanks again DarkQuantum for all you have done in that area.)
• Added a system to translate in-inventory items to other languages (check out game/items.json; only Feather, Wood, Flour, and Grain translated for now)
• Changed trading string “You gain:” to “You will be payed:”
