GooberFirmaCraft

Added Medieval Siege Machines, Medieval Ambiental Music, and added a shaderpack. 
Added Recipes for all of the Medieval Siege Machines and recipes for Cobblestone. They are expensive intentionally, mainly Iron Age weaponry. 


Changed Create to use any Igneous EXTRUSIVE stones in the Andesite Alloy (Might change it over to the bloomery version from SeriousCreeper at some point)
Changed Musket and Flintlock Pistol to do less damage, they should no longer 1 shot mobs (Might one shot players with head shots? Haven't tested yet)


Fixed a few various recipe issues

This is the first RELEASE version, I think the modpack is nearing completion in terms of mods added, there's certainly LOADS of recipes I've probably overlooked and likely some bugs/performance shenanigans that need tweaking but this is what I'll consider my first officially 'Ready' version.
