This seems like a niche feature which can be solved by defining multiple queries. In the future
we'll probably add support for defining series name by alias field similar to how other datasources
have solved that, e.g. prometheus.

Changed Swedish and Icelandic currency

Minor format changes

Just fixed some minor inconsistencies in the format of the file. There were some configurations uncommented like so: 

```
; container_name =
```

and some other like so:

```
;container_name =
```

So there is a need for a small perfection here! 

I also removed some unnecessary line breaks, bullying my eyes...
