Quality recipes

[DaleStan]

These changes allow Yafc to calculate production with quality bonuses and quality input items. Recipes and Items now have quality levels. Several other objects such as Mechanics and Fluids pretend to have quality levels for compatibility, but only ever exist in normal quality.

It covers two of the remaining four tasks in #311, leaving out fixed_quality and quality science packs. Properly consuming quality science packs is next on my list, but they are being obstinate.

Quality modules only produce qualities that are unlocked based on the selected milestones. To make this more discoverable, there is also a new warning message telling the user to "Make sure ... all milestones for the next quality are unlocked." I considered, but later removed, additional code that adds all non-normal qualities as default milestones. If we want to add more default milestones, I can put it back.

I used this project for testing and to trial various possible answers to my most pressing question about quality bonuses, namely: How do I maximize the output of legendary prod 3 modules from a single captive spawner?

Wow, that's a huge feature. This is awesome!

We need to check that Yafc still works with usual mod-lists.
Your test-project covers SE, so the setups that we need to check are:

• Vanilla
• pY Full
• pY Hardmode
• Other overhauls of your choice.

Again, thank you for all the effort you put into Yafc!

Nicely split into the separate commits, helps a lot in understand your (thought) steps
(I didn't start YAFC up to try it)

I had to make a couple fixes for Infinite Quality Tiers and No More Gambling hasn't loaded since 2.2.0.

Otherwise it looks good to me in Vanilla, Omni, py, and pyhm.
