fix adding settings in place in subtabs+solution

I decided to go back to full card interface when editing settings.  You sometimes need to change the type (eg default, content), having the cardname visible helps teach how sets/settings work, and I think it's even helpful just to recognize that all these settings are cards in the first place. Plus it's cleaner in the code.

I did, however, make it so that we're not showing edit help in the new setting values in this view any more -- it's already covered in each setting section.  was very repetitive.
