Tooltip auto right doesn't take parentLeft into account

Created by: RR2DO2

Noticed on Bootstrap 3.0.3. While using the tooltips to use for a chart, which meant manual positioning, I noticed that "auto right" was swapping to left too early. In tooltip.js in the auto placement code

placement == 'right'  && pos.right + actualWidth > parentWidth                              ? 'left'   :

should be

placement == 'right'  && pos.right + actualWidth > parentLeft + parentWidth                 ? 'left'   : 

from what I can tell
