Casey Wilkes a3d2f6592e Add support for colouring tab icon in settings.js ...

```
editorTheme: {
    page: {
       tabicon: {
           icon: "full/path/of/tabicon.svg",
           colour: "#008f00"
    }
}
```

The old way still works also (but doesn't allow the tabicon to
be coloured:
```
editorTheme: {
    page: {
       tabicon: "full/path/of/tabicon.svg"
    }
}
```
