change vnode to Vnode and position to Position in leoAtFile.py.
Restore ability to reorder file tabs.
loadLayouts in free_layout.py now creates free-layout-load-<canonical-layout-name>command  for all existing layouts.  This command can be used in @button nodes, etc, and bound to a keyboard shortcut.  All unit tests pass and pylint is happy.
