#45

This PR is wrong (please decline it), but would like to raise the issue however :)

"type" is not a reserved claim, in fact I found it hard to find (bit of a loaded keyword tho) any info about using "type" claim and could not find anything. Can it be made optional (setting perhaps?)

@IndominusByte any suggestion for better way to make "type" claim optional. Happy to update PR :)

Hi, I've added more options to adjust type claims in #84.
