Added in Auto Save on Focus Lost

[stolksdorf]

Added a toggle-able option to automatically save the file if Abricotine loses focus.

• Will only save if the file has a valid path
• Added the toggle to the file menu
• This setting is defaulted to false
• Uses the internal save method so it doesn't interrupt the file watcher

Nice! This looks good.
I only have one request before merging this PR (see my comment)

[stolksdorf]

Good catch! Missed that when I was figuring out the config originally. Great source code btw, I was able to jump in and figure out how to make my change in under 20min.

FYI I added some changes to this feature in d44bda5.
The autosave is now triggered when the document changes (and not on the "blur" event anymore).
