data-tooltip-source functionality described in readme, but not implemented

Thanks for creating this, it seems like a nice component :)

I tried out the data-tooltip-source thing and wondered why it wasn't working. I examined the source and noticed the code does not know about any tipSourceAttr in reality and has no respective functionality to deal with it.

Maybe you have a local version with this, but did not push it?

Thanks for the issue @mestaritonttu.

Yah, I removed that feature from the script. Thought it might be causing an issue I've been dealing with... though that turned out to not be the case. But after removing it I came to realize it was a feature that really didn't even need to be part of the script in general.

I've removed the reference to it from the readme. cheers :)
