- Added sound + particle effect to crusher when it crushes

- Added thumbnail

-Creep spawn now is standard compared to other maps

- Crusher cooldown time changed from 25s to 20s.
- Hide area is further away from turrets.

- Crusher cooldown time changed from 10s to 25s
- Buttons no longer flash. This gave the impression that the crusher is "ready to fire" which isn't always the case.

- Fixed left obstacle texture sometimes not appearing between back red turrets [hopefully].
- Improved AI in the creep area. They are still a lot braver than I would be in that area so it is something I want to improve further.
- Increased variation in the graphics of the hide area. If procedural hide area graphics are implemented I will likely switch to these.

- Bottom turrets now have more health the the top turrets

- Improved visual and audio feedback of crushers. Should be easier to learn how it works now.
- Added button texture for the crusher.
- AI now has knowledge of the crusher. Whether or not they care is a different story.
- AI has better top lane above turret pathing and should utilise all health packs (center and top health packs were previously not marked).
