Hollow GUI Appleskin support

This is an Appleskin support Add-on for the already existent Hollow GUI resource pack, I loved this pack since the first moment I found it. Sadly, I realized it does not have support for the widely known appleskin mod, so I had to do it myself in order to actually use it, since I am pretty picky with the textures I use, and if there's a slight inconveniece I won't use them even if I like them.

This is how the saturation icons look, keep reading, since I will elaborate further on their looks.

Right order of the add-on, it should be placed above the original Hollow GUI

This support Add-on was made by me and for me, but I thought that it'd be nice if I posted it since I can be sure that more people have wanted to use both this GUI and appleskin at the same time.

I strongly recommend using the Steel Soul Edition over this one, since the saturation icons contrast much better with the hunger icons than in this one, this one was only made for people that wanted to keep the original color palette, but the other version is much more comfortable to look at and to use.

Maybe, in the future, I will make a Hive/Honey based one, since I think it would fit well, no promises though.
