Add type classes on class output

Browse source 
Without this it is quite difficult to differentiate between fill and
stroke elements, f.e. with basic charts with fillings or legends
generally:
`svg path:nth-last-of-type(2).legend`

Text elements needed to be accessed with text.classname which
isn't really best practise.

This way they can be accessed easier:
`svg .legend.fill`
