Tabs Outliner window default position should take into account left-side Task Bar

If the Windows Task Bar is positioned on the left of the screen instead of along the bottom, then the default position of the Task Outliner is underneath the task bar. The default should be just to the right of the task bar. This is not a big deal, it can easily be worked around with the save-position option of Tabs Outliner, but the default ought to be fixed.
