Automatically support c:hidden_from_recipe_viewer for custom stack types

[pupnewfster]

It would be useful if instead of just the builtin types EMI also would also check the hidden from recipe viewer tag for custom stack types when there is a corresponding registry adapter added so that EMI knows how tags of that type work.

This is implemented for stack types whose keys match an existing registry adapter as of 1.1.7, thanks for the suggestion!
