重写材料需求代码

[ProjectSky]

目前解析材料需求的代码过于繁琐，材料添加/修改需要同时编辑neededMaterials和modData表，重写后仅需修改/添加neededMaterials表

新的neededMaterials表结构如下

MoreBuild.neededMaterials = {
	Material = {
		'need:Base.Nails=10',
		'need:Base.Rope=5',
		'need:Base.Plank=5',
		'need:Base.Gravelbag=2',
		'need:Base.BucketEmpty=1',
		'xp:Woodwork=50'
	}
}
