Release v0.6.0

Added

• Hooks the games rendering now to add imgui in preparation for script support (which is still ways off)
• On-screen error printouts
• A watermark with version and all

Changed

• Merged sticker gen with entity merging code, thus full char sheets and regular char sheets work well together
• Make random character select work with full char sheets

Fixed

• Correctly invalidate combined sprite sheets when updating load_order.txt (might have to be optimized in the future)
• Bad size in turkey sheet
• Bad tile pos for journal entry of hired hand
• Small bug that caused a tiny performance loss during startup
