[2021] Please rework Gem Crafting

Hello, i will add a filter to remove already equiped gemstones, i won't remove maxed gemstones because you can use the merging to reroll their stats, also we don't plan a full rework of the system because it's too late for the release but we may improve it post launch

Unfortunately i cannot remove the RNG system as if i remove it just putting two gems would yield the same result as putting 5, it would be a full refactor if i need to change that, i can increase the odds to make it easier and give more rewarding gems but i cannot get rid completely of the rng

Yes i'm going that way, i'm currently pushing a test patch on the "trunk" branch on Steam, should be live in something like 30 minutes if you want to have a look and tell me if you feel it's better now (it's still using the level delta to diminish the chances, meaning that if you put a tiers 1 crystal with tiers 3 crystal it will increase only by a bit the chances but if you put 5 tiers 1 crystal you will have 100% upgrade rate).

It's up on trunk
