description: Handle session states (inactive/active) (#68)
* Add DB migration to insert 'active' column
Inserts 'active' column into the sessions table with
a Default value of 1
* Set active/inactiv state of sessions
Every device that we receive via devicelist event will be set
to 'active', every device in our DB that is not in the received
devicelist event will be set to 'inactive'
* Show inactive session fingerprints in grey color
