Title: HG-258: Fire tracking event for Read more

Action was not executed, so I switched to `data-` argument. To make the `link-to` macro to accept custom argument, it has to be defined in `LinkView.ts`, hence the new file.

Renamed `trackingEvent` to `trackingCategory` as well to be consistent with the `M.track` interface.
