Economy v0.0.17

• Market Browse now remembers the selected Active/All activity filter when closed and reopened. New configurations still default to Active.
• Browse, Active Orders, and Trade History remember their product filters, order/trade filters, and sorting in config/economy-client.properties, including across client restarts.
• Added regression coverage across all supported Minecraft families for every saved selection, defaults, invalid values, and preservation of other client preferences.
