Truncates long labeltree descriptions to prevent overflowing content.

Thanks! So this is only a problem if there are no spaces in the description and the browser can't break the text, right? This will probably be more of an edge case.

I think the description should be displayed in full in the project list. This is what the description is for, after all. So instead of truncating it all the time (even if it has spaces and can be broken nicely), maybe we should rather use word-wrap: break-word instead. This will break long words without spaces so they don't overflow the element.

While you are at it, you could do the same with the label tree title. And also on the label tree overview page:

I've merged #953 into this branch to fix the JS action errors.
