v1.8.3带来的EOS REX的变化

变化总结：

更长的解锁时间，更多的资源可以被借出

REX池有四个资源：

-CPU，NET贷款
-RAM交易费
-名称拍卖出价
这些收益将立即按比例分配给REX。
在v1.8.3中，它将从收集到REX阶段的收益开始的12小时内，在30天内线性分配时间。
REX->下限unlent余额->高租金（防止价格过低）
先前版本：
-未借出token不能少于已借出token的20％
-未借出token不能少于总token数的1/6
卖单队列：
-将卖单延迟到卖单队列中，以不触发下限
1.8.3版本：
-未借出token不能少于借记token的10％
-未借出token不能少于总token数的1/5

Change Summary:

More unlent duration, more resources will be lent
