Basic D-Bus API (#866)

* feat: basic D-Bus API

Expose muted state and the number of unread message over D-Bus when
running on Linux. This is useful for, e.g., displaying notifications on
a window manager status bar.

* docs: create docs directory

Move the documentation to a separate directory so that new documentation
can be added into one place.

We keep the following files still in the repository root by convention:

* CHANGELOG.md
* CODE_OF_CONDUCT.md
* CONTRIBUTING.md
* LICENSE.md
* README.md
* SECURITY.md

* fix: remove unneeded D-Bus signals

Only notify clients that the message counts or the mute status has
changed if there actually was a change.
