Beta release 5

0.3.6 Beta Release 5

Added

• The Picamera2.global_camera_info() method will return information about all the attached cameras.
• We have introduced the ability to control multiple Picamera2 objects (all opened for different cameras) within the same Python process. They behave independently and can each have their own preview window.
• There is now limited support for USB webcams that deliver MJPEG or YUYV streams. Images can be displayed by the QT (not QTGL) preview.
• Picamera2 objects have a title_fields property which can be set to a list of the metadata fields to display on the preview window title bar (for example `picam2.title_fields = ["ExposureTime", "AnalogueGain"]).

Changed

• Resources are freed more reliably when Picamera2 objects are closed.
