[texworks] message from TeXworks user(What about auto-save?)

[Đức Minh Thái]

I think the option is quite reasonable, like Vim does, it has an optional 
swap file while we are editing. When things go bad, we have most of our work 
restored. TeXworks is now very stable, but if some things went wrong, it may 
crash. So the auto-save is a good feature to have, especially when working 
with large project/file.

Pressing the Ctrl+S after a paragraph might be annoying and disturbing when 
you're not yet completing your idea.
