Font awesome now provides a different approach to icon styles so you can
specify things like:
```
<i class="fa fa-camera-retro"></i>
```
but also
```
<i class="fa-solid fa-camera-retro"></i>
```
The original implementation had a hardcoded `fa` and having an extra
parameter for the *style* seemed overkill, as we would need to handle
even a list of styles like on this example:
```
<i class="fa-sharp fa-solid fa-camera-retro"></i>
```
So I chose to just explicitly require the full FA icon class and pass it
thru. With no manipulation on the Vue side.
This patch does that, and adjusts the 'style' for some icons, as
introduced by the FA v6 patchset.
