Log the texts the player has seen, make it accessible

It might be useful to provide access to a history of all the monologues the player character has spoken. It might be more user friendly to browse a history to see if you've missed some essential hint, rather than having to click through everything again. Additionally, some texts are only accessible once (such as pick up texts).
#45 is probably useful for this.

Start by reviewing issue #45 and the existing handling of monologues and one-time texts. The issue does not name files, tests, or entry points, so the implementation scope must first be established. Done means the player can access a history of all spoken monologues, including texts that are otherwise accessible only once.
