Moved rendering to PholioInlineCommentView

Summary:
Rendering of inline comments has now been moved to PholioInlineCommentView controller.
Delete almost deletes and edit... well not so much, but replaced google.fi with amazing popup.

Test Plan: Verified that inline comments still show up. Verified that delete almost deletes.
