Change recipes to use FU salt instead of MFM salt

[ColonolNutty]

Update patch files to use the new price for salt, or possibly change the price of salt in FU to be the same as MFM so there won't need to be a price update.

Perhaps the price doesn't matter, however I could add recipes to convert FU salt to MFM salt and vice versa. Then I could copy the MFM recipes containing salt and use FU salt in those.

Alternative to that, I could implement an "alternative" ingredient system. So that any recipes using MFM salt can automatically also use FU salt. Maybe a json file is read that contains the list of alternative ingredient mappings. Like:

{
    "saltMFM": ["saltFU", "saltBlah"]
}
