Use new custom RSS field for News Insight titles
Currently a dedicated field is used for News Insight descriptions, but not for the title. Unfortunately there are different needs for the title length in Lightmeter vs Lightmeter.io, so using a separate title would be best.
This has already been added to Lightmeter.io RSS feeds, element name: lightmeter:newsInsightDescription
. All that remains to be done is to switch the title used in lmcc from the main post title to the newly added XML element.
