#9 Encryption

[Tim Horton]

Someone suggested this because apparently there are a few people who
write usernames/passwords for their online services on Internotes:
encrypt the stickies file!

I'm not sure how hard that would be (I can't imagine it would be /too/
bad) - but I'm also not sure how good of an idea it would be. Right now,
one bit gets flipped, you lose one note. With that, you'd lose everything
(with the current all-notes-in-one-file system)!

This is for the community to decide. Or: make it optional (annoying and
possibly bug-full to code, but better!)
