Liferay 6.2 改造系列之二十：修改默认添加用户权限及用户是否拥有个人站点的配置

1、修改默认添加用户权限为User，而非Powers User：

在/portal-master/portal-impl/src/portal.properties文件中有如下配置：

#
# Input a list of default role names separated by 
 characters that are
# associated with newly created users.
#
admin.default.role.names=Power User
User

修改为：

#
# Input a list of default role names separated by 
 characters that are
# associated with newly created users.
#
admin.default.role.names=User

2、修改默认拥有个人站点的用户权限为Powers User，而非User：

在/portal-master/portal-impl/src/portal.properties文件中有如下配置：

    #
    # Set this to true if users must have the Power User role to have private
    # pages.
    #
    layout.user.private.layouts.power.user.required=false
……
    #
    # Set this to true if users must have the Power User role to have public
    # pages.
    #
    layout.user.public.layouts.power.user.required=false

修改为：

    #
    # Set this to true if users must have the Power User role to have private
    # pages.
    #
    layout.user.private.layouts.power.user.required=true
……
    #
    # Set this to true if users must have the Power User role to have public
    # pages.
    #
    layout.user.public.layouts.power.user.required=true
