Add option to blur thumbnails

[mountaindude]

Summary

In apps that use section access to control who see what data the thumbnails could become a security risk.
If the thumbnail was created with a high-privileged user account, the thumbnail could be showing miniatures of data some users should not be able to access.

The easy solution would be to add an option that blurs the thumbnail before it's uploaded to Sense.
The level of blurring should be configurable.
Should also be possible to specify which sheets should get blurred thumbnails. Using the same filtering criteria as when excluding sheets would make sense.
