Optional Widget for Linux Lite 3.2

[Valtam]

The widget needs to be as minimal as possible. The approach here is to allow people to glance at a space on their desktop and get simple, concise information. For example, if they're rendering a video and want to know their cpu usage, or how may updates there are.

For there to be transparency, compositing has to be enabled, and in LL it's turned off by default due to some older pc's not able to handle it.

Thanks @firenice03 for your suggestions, I like the idea of making the widget even smaller.
