Pholio - render inline comments together in an email

Summary: Used Differential emails as a formatting guide. This also includes "Image X: <inline comment>" similarly to how Differential has "<file path><line(s)>: <inline comment>" or what have you. Fixes T3138.

Test Plan: inserted some debugging code and verified the mail body format looked okay ish
