Pasted images removed from note but remain on hard drive

[Brian Marquez]

If you paste an image from the clipboard into a document, a file called ./pasted_image001.png is created. However if you delete the pasted image from the note (by pressing backspace), it remains on the hard drive. If you do a lot of pasting and deleting, for example in a temporary scratch pad, the folder will fill up with pasted_imageXXX.png files which aren't linked to anything and take up space.

Perhaps pasted_image (or even other types of attachments) that are no longer linked to a note should be deleted? Or some other method of cleanup.

This is using Zim 0.67 on Windows 10.
