Subject: Improve comment RSS feed visibility, initially added by Thomas E.
 Horner in fc942aacda07346fa9af04853659eaeac1e766d3.

Change some variable names, refactor out visibility checking code, actually
check visibility at generation time instead of just suppressing the UI,
update module.info

Fixes #1829.
