Changes things to be less annoying and intrusive on your screen, i.e. pumpkin blur, spyglass overlay, rain, fire

List of changes:

• No pumpkin overlay
  
• No spyglass overlay
• More transparent rain
• Lower fire (block and screen overlay)

Partially inspired by this and this pack, as well as the many pvp packs that lower fire.

Progress is set to 95% as I'll very likely add some more content later.
Feel free to use this in other packs or to port, with credit please.
