## Issue
~300KB savings in `ui.js` size (production, uncompressed). Mostly coming from the emoji library.
## Notes
Most of the `Comment*` components are under `CommentsList` or `LivestreamComments`, so deferring these 2 covered most of it. The exceptions are Notification and OwnComments.

## Changes
I meant to only add the macro at the client call during the refactoring, but forgot.
Having said that, I now think it's cleaner to put the macro where it is defined, and it's easier for Translators to find, so I added the macro in the definition instead of at the client call.
