Can't change first page about gamebookengine

[amiantos]

This is an interesting problem. We don't really want to just allow people to get into a bad state. So letting you turn off the first page at any time wouldn't be great, it would break the game entirely and probably the app to some extent. And letting you turn on first page on any page, so there are temporarily two pages, seems rife with peril as well. Really we need a special function for changing what the first page is, so that they can be swapped and saved to the database at the same time. We can probably use the page list/pages view to allow you to pick a new first page and then do the swap, might not be a big lift.

A question of data integrity: Should a newly created first page have any decisions leading to it removed? No, games can loop, it shouldn't be assumed that the first page has no pages leading back to it by default. I think when a page is anointed the first page, no changes need to be made to it...

Not sure why it wasn't obvious earlier but... if you're on a page, and you hit "first page" to change it to the first page, it should just prompt you then that this will swap the first page in the game to this page... easy peasy.

Okay, so I got this rigged up, it'll turn off the current first page and then set the new page... but it seems to not play nicely with the page visualization interface, like it's not redrawing the full graph, probably need to do something special there...
