Views: update the "core" version in all core-provided views config files - or remove it completely

[klonos]

Current situation:

views.view.comments_recent => 0
views.view.file_admin => 1.6
views.view.image_library => 1.7
views.view.node_admin_content => 1.0
views.view.promoted => 0
views.view.taxonomy_term => 7
views.view.user_admin => 1.0-dev

If this is not being used by core or contrib, then lets remove it. If it is used, then we should make sure that it is accurate.

I believe that this core value is there to indicate the version of Views used to create the view, and can be used for compatibility purposes. The version number:

• should be the actual version of Backdrop at the point in time when this view was introduced
• should not be a dev version
• should not be 0
• should not be 7

Side-task: Should we be updating this value each time a view is saved, in order to indicate the version of Backdrop core at the time it was updated?

+1 for this idea :)
