Major Update!

Hey Everyone,

I hope everyone is doing well in these strange times. Here is a relatively big update for the game.

- Added LUT (colour look-up table for post processing colour adjustment).
- Added a plant preview. When a player now holds a seed/spore bag over an acceptable garden patch a preview of the fully grown plant will be displayed.
- Changed brick material.
- Added seeds to extend how long a pigeon stays around for (Feed them with the interact button, default is "E" for keyboard).
- Added pigeon whistle to call the next pigeon in the queue.
- Added an outside.
- Moved poetry book outside.
- Upgraded engine to 4.24. This fixed a wall seam visual issue that was introduced with the last upgrade to 4.21.
- Added it so if you accidentally take something out and don't want it you can just put it back by dropping it over where you took it out. If you put a quest or reward letter in one of these spots it will just get reset to it's original table.
- Added auto-detect optimal quality settings to main menu. This is just a one click to set up the optimal settings for the game based on your computer.
- If you manually put textures or shadows on low then decorational decals will be removed.
- Added sunbeams.
- Added various sound effects.

Known issues:
All platforms:
- 1 Planter outside needs collision adjustment. Flowers can still be planted in it but grown plants fall through it. To be fixed in next update.

Linux Specific:
- When using the auto-detect quality setting it doesn't seem to be able to read a screen resolution. It will default to 0x0 (in the options menu) and this will need to be set to a value before any options are changed.

Potentially fixed:
- Linux users were having high mouse sensitivity problems. This was fixed in my tests of the newest build for myself as I noticed the mouse sensitivity was lower playing the game than using Ubuntu. It seems to have been an Unreal issue as it was fixed with the engine upgrade to 4.24.
