I have added the ability to include skein and lyra2z coins into json response.

Just need to include those extra params:
&factor[sk_hr]=xxx&sk=true&factor[sk_p]=xxx
&factor[l2z_hr]=xxx&l2z=true&factor[l2z_p]=xxx

You can also hack those coins into UI response using the same params. Add "&dataset=xxx" to save into tab for easy click access.
Please note that pressing calculate will remove those coins from response, as forms are not yet present.
