Allow for fields in categorized theme.

[dbauszus-glx]

It should be possible to apply a categorized theme on multiple fields.

This currently works only for icons.

The styleParser checks that the categories have a field included in the fields array.

The cat style must be an icon which is not an array. It's possible to alter this requirement later but I would need a valid test case for this.

The styleParser icon check was expanded to not merge into icons which have a type or are svg to prevent type:dot icons being merged into type:template or svg icons which would break the icon.

The cat.field is assigned as field instead of the theme.field in the categorized legend iteration of the categories.

[dbauszus-glx]

I'll now flatten style.icon with icons array.
