Export Draft dialogue needs (de)select all

[amberv]

I did not see this on the To Do list, so forgive me if it is already there, but when exporting the Draft, you are presented a checklist with all document nodes in the Draft. I realise that there will be a contextual export at some point, that only exports the current folder and below, but I think there should still be a "master" check-box that toggles the selection state to off or on for everything. This should be a state persistent thing, too. So if you are working on two specific parts of the project for a few weeks (which would not be addressed by a contextual export) you wouldn't have to reset this option every time you exported a print for editing.

Incidentally, the same feature should exist for page breaks. If I want page breaks after every chapter, it is kind of a pain to set that up right now.
