Support adding folders to referenced libraries

[gerrywp]

settings.json

{
    "java.project.referencedLibraries": [
        "lib/**/*.jar",
        "D:/WEAVER/ecology/classbean/**/*.class"
    ]
}

这样的配置无效，或者.classpath里面配置也是不支持的

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
    <classpathentry kind="lib" path="D:/WEAVER/ecology/classbean"/>
</classpath>

classbean目录下面有生成的.class文件，比如classbean/com/api/workflow/user.class
