Option to save on focus-out only

[Tom Beckmann]

I'd suggest to only save on focus-out, since it practically makes no difference, it just reduces the number of writes.
Using Scratch heavily often makes my computer do weird noises.

I really appreciate the disaster-proof nature of Scratch file saving. And data integrity is typically valued more than performance; for example, disabling all the data integrity mechanisms in the file system yields a ~5x performance boost, yet nobody does that.

However, laptops have built-in UPS (battery) and dislike frequent disk writes for power usage reasons, so maybe we could detect if a battery is present and disable save-as-you-type. But even then I'd use saving every 30 seconds or so instead of completely disabling it.

We could still add something like a 10s timeout after inactivity for doing an autosave, but not on every single key stroke I think.

autosave how it is now must remain in Scratch. I can add an alternative to it however just saving files where the SourceView is focused out.

Sounds good. I consider this bug's priority pretty high though, my old computer doesn't really like constant saves :(

I've added saving on focus-out and increased the typing break saving timeout to 3 seconds. This should fix the original issue while still maintaining a decent degree of crash-proofness.

Looking at how stable Scratch has been recently, it might be a better idea to move away from the typing break timeout and just save the file every 30 seconds or so if the was changed (and keep the saving on focus-out, of course).

Sounds like Fix Committed
