Infinite scroll mode in listing

[Chalarangelo]

• Add infinite scroll (with some sort of URL-based pagination) in listing pages
• Enable by default
• Add option in the settings - Settings menu #69 - to allow change of defaults
• Handle impact on analytics
• Customize loading snippet page logic and going back to listing page scroll location
• Add a back to top button, if necessary

After a lot of consideration and mock implementations, I have arrived at the following:

• Infinite scroll should be dropped in favor of a "Load more" version.
• Pagination should still be available via settings, but the "Load more" version will be the default.
• We will be using some tests to identify bots and serve them pagination by default, while users will be served the "Load more" version by default.
• Logic for going back and forth from snippets will be handled via a "Load previous" button at the top. This will only be shown when users open a snippet page and go back or after they have loaded more than X pages (TBD).

After some more research and hitting multiple walls during implementation, we will not be implementing this feature after all. Instead, we will opt for a pagination redesign that will be friendlier to the user and we might also update the amount of snippets shown on each listing page.
