Ardour updated to v5.9

Ardour 5.9 is now available, representing several months of development that spans some new features and many improvements and fixes.

Among other things, some significant optimizations were made to redraw performance on OS X/macOS that may be apparent if you are using Ardour on that platform. There were further improvements to tempo and MIDI related features and lots of small improvements to state serialization. Support for the Presonus Faderport 8 control surface was added (see the manual for some quite thorough documentation).

As usual, there are also dozens or hundreds of other fixes based on continuing feedback from Ardour users worldwide.
