Periodically encrypt most recent notes and submit to IPFS

[hadasz]

As a user, I want to know my notes are safe in external storage in case I lose my phone.

Acceptance

• Data is chunk'd
• Data is on IPFS
• Data is encrypted
• Reconstruction requires everything, a single piece can't reveil anything new
• Reconstruction "instructions" are non-public

Question
How often do we save notes?

...and so that I can run multiple devices the way I have come to expect with most Cloud-based apps without causing significant problems of messing up my files because I was editing at the same time on multiple devices and corrupted the file.
