Added support for Applied Energistics 2

[JamesYeoman]

In order to add the support, I had to update the forge version as AE2 requires that version as a minimum.

I'm not exactly very artistic so I used the Sapphire Chicken model as a base and an RGB Gradient site to change the colours of it to a more certus-quartzy pallete.

@GenDeathrow You might want to consider adding a .editorconfig file at some point to enforce code style. I found various conflicting styles when exploring the code.

One particular thing that would benefit from the .editorconfig is whitespace. I discovered that there're places that are indented with a mixture of space and tab.

Also, I have an idea for how to implement extensibility that wouldn't involve PRs. Basically, by utilizing Java Annotations, it could be possible to dynamically load in chicken definitions from the classpath.

I imagine an addon chicken class would look something like as follows

import com.gendeathrow.morechickens.api.annotations.MoreChickensAddon;
import com.gendeathrow.morechickens.api.interfaces.IChicken;
import com.gendeathrow.morechickens.api.Utility.*;
import net.minecraft.util.Tuple;

import static com.gendeathrow.morechickens.api.Utility.getChickenById;

// requiredModId would be an optional parameter with a default
// value of "". Then, when loading all the chickens, a `Loader.isModLoaded`
// check could be done
@MoreChickensAddon(requiredModId = "appliedenergistics2")
class CertusQuartzChicken extends IChicken {
    @GameRegistry.ObjectHolder("appliedenergistics2:material")
    public static final Item certusQuartz = null;

    public CertusQuartzChicken() {
        super("Certus Quartz Chicken", "certusQuartzChicken", "textures/certus_quartz_chicken.png");
        this.setBgColor(0xb4d9fd);
        this.setFgColor(0xbfceda);
        this.setSpawnType(SpawnType.NONE); // Utility.SpawnType
        this.setLayItem(new ItemStack(certusQuartz, 1, 0));
    }

    // The reason for it being a method rather than a property
    // is because all the chickens need to be created first.
    // That way, chickens can have parents that are also created by the addon.
    // E.g. a Fluix Chicken that has parents of the Redstone Chicken and the Certus Quartz Chicken 
    @Override
    public Tuple<IChicken, IChicken> getParents() {
        return new Tuple(getChickenById(VanillaChickens.Quartz), getChickenById(VanillaChickens.Glowstone));
    }
}
