[AO3] Mark for Later - Skip the Click

A straightforward, simple script that does exactly as it says on the tin. A clock/timer-shaped button appears next to the date on every listed work in search results and similar, where when clicked, it will automatically add the work to your "Marked for Later" list. Oddly, the website seems to already partially support this feature, so it was very easy to set up.

See below for a visual reference of the new button (on my skinned version of the website).
