There's nothing stopping somebody from running this alongside an older version of BuildCraft which may cause unexpected issues if its prior to BuildCraft 7.1.6.

At a minimum, need to add BuildCraft|Factory to requiredMods list in mcmod.info

Additionally, need to test to see what happens when running IrontTank alongside BuildCraft 6.x. If it results in bad behavior (likely just from #6) then additional checks should be added to prevent users from harming themselves with unsupported combinations.
