Even more QoL and some adjustments

I made a few tweaks and added a bunch of stuff:

Option to read the tutorial in the main menu, most people press "Understood" without even reading xdn't... So you can now rewatch that :)

You can also end the round sooner by pressing the button that says... well... "End Round", ofc.

I also adjusted the pricing for the preacher, as with the previous one it was impossible to unlock it while playing normally, so everyone would just unlock EVERYTHING else before moving on to the preacher, that's not the goal, it should be more of a "oh! new branch!" kind of experience.

I also improved the lagginess a bit, it was mostly caused by the harvester and the Strikes, and it was not actual lag but rather some weird visual effect, unfortunately I had to remove the infinite rotation for the harvester, but I improved its feedback by adding a semi-transparent area inside it to show when it's activating, so it should be easier to calculate the attack intervals now.

The preachers will now spawn further away from each other and will TRY to avoid the pit as well as each other, you cannot stack their effect to gain more guilt so it was really annoying when they stayed together all game long.

You can now deactivate the CRT effect in the upgrade tree, I didn't know it looked so bad but goddamn, I tried it on an older laptop and wanted to throw up, sorry for the late addition for such an important thing!

Lastly, I fixed a bug that let you harvest when pressing play again and increased the harvester area a bit because it felt really unfair when it wouldn't hit minions that were clearly touching the border.

And if you're reading this, I have a reward for you: here's a spoiler for the next BIG update!

That's right people! We're getting a base for our cult!
