This is mainly a bug-fix release. Most importantly:

- A regression has been fixed which was preventing rolod0x from automatically activating on the built-in list of sites.
- Upgrades have been fixed to no longer accidentally discard old address book labels. Many apologies if you lost data during the upgrade to v1.5.0 - this was definitely NOT intentional and we'll do our best to avoid this in the future!!
- A regression to settings navigation was fixed.

High-level user-facing changes:

- add an onboarding tour
- add support for multiple address book sections
- add support for fetching address book sections from a URL
- add a Paste button
- add import/export of settings
- enhance the list of built-in sites
- numerous minor UI/UX improvements
- doc updates
