Show the load more comments button any time the last comment page was filled to the requested limit. As noted in the comment, this heuristic will be wrong at most 5% of the time but the failure mode (showing load more which, when clicked doesn't load any more, just goes away) is very mild, and for the overwhelming majority of project views that happen on projects with many, many comments, this is very unlikely to ever be noticed. It obviously isn't a perfect solution, but I cannot think of another that does not need the server to do another query to find out the total number of visible comments, or to find out if there are more comments after the requested offset+limit.
* Initialize `locales` in redux using methods exported by GUI.
* pass GUI method to set the `scratchlanguage` cookie
NOTE: It does not reload the page, so switching back to the project page will not reflect language changes made in gui until the next page reload. Reloading the page will lose project state so we don’t want to do that.

* pass to and receive from GUI info about project lifecycle
* reset project data or fetch new project data depending on updates received from gui
