import/export from json about qboard

[pihart]

Should it preserve history or should "load from JSON" be a single history event

[cjquines]

dont think preserving history is worth it? not as if we keep the whole history tree. and it's also truncated past a certain number of items

todo: expose this in the ui

i still disagree with this being in history. in fact, i dont think importing json should append pages, but rather, replace the entire document; it should be analogous to opening and saving a file ui-wise. i also don't really see a usecase for this; qboard was never intended to work with multiple documents, and was always supposed to be for presentations (and i guess, now, scratch work). so i'm not sure if i'll keep the splicing pages thing

[pihart]

One thing I wanted to add was a check to see if the open document is new (as in the union the pages contains no objects), and in that case, don't append but overwrite.
