Need to make clicking on 'Link >' in popup on chart bar/wedge open in _parent (do #93 first)

[rouilj]

This is similar to #76. The copy of pygal-tooltips.js coming from my server is modified to open 'Link >' in new tab for debugging.

The current code uses an embed tag to show the chart. As a result the unmodified "https://kozea.github.io/pygal.js/2.0.x/pygal-tooltips.js" opens the link in the embed, not in the window.

This patch to pygal-tooltips.js forces it to open in the parent window.
