New

Local socket connection support has been added to Euphonica. Named sockets should probably work already, I guess?

Bugfixes

• Fix "Queue all" in playlist view queuing twice.
• Worked around Queue View & Playlist Editor scroll position resetting upon row removal.
• Restored startup connection error pop-ups.
• Fix Queue View subtitle not updating upon clearing queue.

Refactors

• Moved folder view state code into library controller (finishing what the background client PR started). As an added bonus folder view now retains state across window launches when background running is enabled.
