Quickly update WebPart titles by CSOM

While entering content for a new SharePoint section on a SharePoint 2010 publishing site, the content editors added a related articles webpart on about 100 pages. Too bad they didn't bother to change the webpart title, so I was asked to change change these titles, which had their default value, from a rather functional description of the webpart to something that makes a lot more sense in on the pages. As it should be possible to do it in CSOM, I created a small console application to achieve this.
