Swedish translation for Tabs & Accordions

Hello Peter!

I just saw that the Swedish translation of the theme Pills for Tabs & Accordions is incorrect.

This is how it is translated now:
Pills = Pelare
Pills Colorful = Färgade Pelare
Pills Dark = Mörka Pelare
Pills Light = Ljusa Pelare
Pills Minimal = Minimala Pelare

It should be translated like this:
Pills = Piller
Pills Colorful = Färgade Piller
Pills Dark = Mörka Piller
Pills Light = Ljusa Piller
Pills Minimal = Minimala Piller

The Swedish word Pelare = Pillar/Column (Pilaar) and you really can't associate them with that.

I would like to make the changes to my current language file before there is an update. But where do I find it and what is it called.

Regards
Tage
