Plants vs. Zombies: Cubed

- NEW PLANT: Added Squash
- Increased Cherry Bomb's Targetting Range to 12 Blocks.
   - This basically makes Cherry Bomb an Instant-Use Plant if there are zombies nearby, while allowing the player to keep it around if they want to.
- Right-clicking a Puff-shroom with a Small Sun prevents it from dying by age. Nerfed Dying Time to 2 minutes.
   - In the same idea of allowing the player to keep their plants, you can now have Puff-shrooms linger forever. If you wanna have a lil mushroom friend, you can now :)
- Improved Hypnotizing logic.
   - Hypnotizing is now much smoother and instanteneous, instead of the awkward mess that was before that. Sometimes it delayed the hypnotization and made hit noises, no more.
- Added Roof and Sand Tiles and reorganized the Tiles tab to be in order of chronological game appearance.
- Added Snow Queen Pea and Ice Spike Projectiles to the Plants creative tab.
