[Feature Request] Backup source files

[dragokas]

Hi,
not so often used feature, anyway.

Recently, when my light was suddenly turned off, sp file was entirely replaced by NUL characters. By luck, I just made a manual backup before it.

Can you, please, make a feature similar to N++, so when you "Save" any of sp, it is automatically get copied to a folder "Backups" with a "Name_Date_Time.extention".

Much thanks.
