Describe the bug
I've gotten both Simpleores' and Railcraft's copper. They are different, and have different available recipes.

To Reproduce
Get both copper ingots, press U (default key for finding uses of block/item) while hovering over it to see the available crafting recipes.

The below are items I've noticed that require simpleores:copper_ingot and do not accept railcraft:ingot:1 (copper ingot).
quark:pipe
All of the harvest craft bakeware like potitem, bakewareitem, saucepanitem, etc..
railcraft:ingot:8 (brass ingot)
contenttweaker:material_part:4
betterwithmods:material:34
simpleores:copper_block
There don't seem to be any items that require railcraft:ingot:1 and not simpleores:copper_ingot.

Expected behavior
The copper ingots should have all identical available crafting recipes. They should be treated the same. Even if you don't intend on players being able to get one, you should still be using ore dict entries in recipes so this problem can't come up.

Info (please complete the following information):

• Modpack Version: 2.77.1
• Server or Singleplayer: Server
• Version the world was created on: 2.77.1

Additional context
It's a simple fix. You just need to go through the recipes and replace almost every instance of <simpleores:copper_ingot> with <ore:ingotCopper>, obviously leaving it as-is on the output of crafting recipes.

We don’t have Railcraft in the pack. You added that yourself. Case closed.

If we ever add another mod with another type of bar, of course we would add oreDicts, we know what we’re doing. But we don’t intend the pack to be played with other mods, so we won’t do that work (of which there would be a lot) until we need to. Feel free to make a PR though!
