One2many Mass Select/ Deselect Widget

If we want to Select/Deselect a few order lines from a lengthy Sale Order/Purchase Order (Case: 10+ Order lines), We have two ways, individually delete orderline one by one from Purchase/Sale order or create a new order. This module eliminates this issue by introducing a new widget "Mass Select/ Deselect Widget"; which can be used in any One2Many fields to perform mass select/deselect .
