fix loading of regions in older session files

Browse Source 
In session file formats earlier than 7000, region position and length
are stored in distinct XML node properties. For 7000 or later, both
position and length are part of the "length" member. Fix reloading
this by noting session file format and loading position and length
more explicitly
