Add history sync, resolves #13 (#31)

* Add encryption

* Add login and register command

* Add count endpoint

* Write initial sync push

* Add single sync command

Confirmed working for one client only

* Automatically sync on a configurable frequency

* Add key command, key arg to login

* Only load session if it exists

* Use sync and history timestamps for download

and it's not an easy one to google.

* Simplify upload

* Try and fix download sync loop

* Change sync order to avoid uploading what we just downloaded

* Multiline import fix

* Fix time parsing
