Title: Add CSS pseudo-class 'nonempty' for workspaces containing at least one window

Still needs some work, but it's a start. In particular:
* only applies to grid mode, not single-row mode
* only useful after adding the 'nonempty' pseudo-class to the Cinnamon theme CSS

Here's the relevant section from cinnamon.css:
```css
#workspaceSwitcher {
spacing: 0px;
padding: 3px;

}
.workspace-button {
width: 20px;
height: 10px;
color: #cccccc;
background: #888;
border-left: 1px;
border-top: 1px;
border-color: #555;
padding: 2px;
}
.workspace-button:outlined {
padding: 1px;
background: #dd7700;
color: #555;
}
.workspace-button:nonempty {
padding: 1px;
background: #bbb;
color: #555;
}
.workspace-button:outlined:nonempty {
padding: 1px;
background: #ffb048;
color: #555;
}
```
