Summary: When the pointer device gets plugged off the cursor is hidden, when a pointer device gets plugged in the cursor is shown again. This allows to easily turn a tablet into a proper system by showing the cursor only when it makes sense. Test Plan: Tested on exopc with external mouse Reviewers: #plasma Subscribers: plasma-devel Tags: #plasma Differential Revision: https://phabricator.kde.org/D1682
