Consider echoing settings back to UX on changes

[Mrcubix]

Description

To ensure changes made outside of the UX or during the SetSettings are properly synchronized, we should consider just invoking the Daemon's Synchronize event at the end of SetSettings.

Currently it is only done if SetSettings has failed at a specific point.

This would avoid the use of plugins such as UX.Remote which hijacks the UX to synchronize its state.

(Usually plugins can't access the UX, but this take advantage of the fact the UX also load plugins & instantiate them when enabled.)
