Bug Description

The external libraries used in the word engines are never cleaned up when closed by the QPluginLoader, this results in the keyboard using an additional 2-3mb of RAM every time the layout is switched.

Steps to reproduce

1. Enable multiple layouts

2. Switch between them repeatedly

Expected result

Memory usage should level off to a constant amount

Actual result

Memory usage continues increasing with every layout switch
