Asset nodes now have a new field called "properties.duration_seconds". This holds a copy of the duration stored on the referenced video file and stays in sync using eve hooks.
To migrate existing duration times from files to nodes you need to run the following:
./manage.py maintenance reconcile_node_video_duration -ag
There are 2 more maintenance commands to be used to determine if there are any missing durations in either files or nodes:
find_video_files_without_duration
find_video_nodes_without_duration
FFProbe is now used to detect what duration a video file has.

Apparently Eve is now stricter in checking against MONGO_QUERY_BLACKLIST,
and blocks our use of $regex when getting child nodes. See
`jstree.py::jstree_get_children()`
This 'custom view' means that the URL to view the node (as returned by
url_for_node(…)) cannot be loaded via XHR and embedded in the project
viewer, but should rather be used as the actual browser URL instead.
Currently only blogs use this.
