Green Background Removal + TSX Generation + Bug Fixes

Removed green backgrounds from 30 tileset PNGs (16.4M pixels!)
 Created mass TSX generation script for 3877 individual objects
 Fixed TiledTestScene cursor crash bug
 Added micro_farm_8x8 JSON loading support
 Documentation: GREEN_BACKGROUND_FIX.md, MASS_TSX_GENERATION.md

Scripts:
- scripts/remove_green_background.py (batch transparency fix)
- scripts/generate_mass_tsx.py (3877 .tsx files generator)
