Configurably attach icons as payload to notification packages. By
design and due to restrictions on mobile devices *only* png is sent.
As KIconLoader preferably returns svg icons from iconPath() we fall
back to loading from "hicolor" using KIconTheme directly. Otherwise
*many* icons are dropped because of svg format.
This also improves slightly the test-case to use a tweaked TestDevice
to allow for inspecting sent NetworkPackage-s.

Added kcm ui with global and app-specific config options.
Global options affect all notifications:
- Persistent only? --> Sync only notifications with timeout == 0?
- Include body? --> Add body string to summary when syncing?
- Minimum urgency
Per-application options affect notifications sent by a specific
application:
- Sync it at all?
- If yes, allow to define a "blacklist" pattern (QRegularExpression)
to define which notifications should *not* be synced.
Applications are maintained in the per-device config and added when
seen the first time by the notification listener. From that moment on
they can be configured in the kcm ui.
Eavesdrop on the Notify call of the org.freedesktop.Notifications
dbus-interface, proxy all caught notifications to our peer device and
track them in the internal notifications-list.
Also fix "cancel" requests from peer devices, by cutting of
kdeconnect-android's id-prefix.
