PNG image export adds {{js}} tag

[ssldhl]

I am using node-export-server in my node js app to export highchart graphs to png. But, there is a slight bug that writes {{js}} on top of image.

One thing that I have found out is, while exporting svg this problem does not occur and highcaharts.com link gets placed at bottom, but in png the link disappears and {{js}} tag gets written.

Hi, this was fixed in a push yesterday, and was just published on NPM as well.
Re-installing (or git pull if you're not using NPM) should fix the issue.
