Change "Abandon Quest" to "Skip Tutorial" in pause screen

[wjt]

It is valuable that you can abandon the tutorial quest, e.g. because we want to get someone straight to Fray's End to talk to the StoryQuest Elder.

But it would be clearer to have the pause menu item be labelled "Skip Tutorial" rather than "Abandon Quest".

We need to grant the player the abilities they would have got during the tutorial if they skip it.
