Another bug fix release.
Went deeper into the open at further right inconsistency problem of Kyle Collins.
Not really sure is it V91 or my miss as I can't remember if it was working ok before.
First I notice the inconsistency only when the tab close option is set to default.
Found that in the code if tab close is set to default will result in saving a value as 'undefined'.
Wrapped that code in a checking if block to not do that block for tab close default.
Seems to be working right now.
Tab Groups I'm not so sure about this.
Moving tabs, this one I'm looking into next.
