Remove Potion Cauldron restriction for Paladins and Rangers

[Diabl0658]

From the wiki: "Paladins and Rangers can only brew one potion at a time, even with a potion cauldron."

Now that they actually have to spend one of their limited feats on Brew Potion, maybe such non-optimal builds could be rewarded a bit by having the restriction lifted so they can brew in batches like everyone else?

Also: could paladins get cure moderate wounds as a 2nd level spell instead of 3rd?

not sure why potion cauldron restrictions exist at all honestly

let's just make every character able to brew up to 10 potions in them
