Keep license structure (#440)
What happens is that license is handled as string, that later deep below (in XmlWriterUtil, from plexus-utils) is stripped by Line Separators (hence paragraph lines are gone) and spit into string. Instead, make this a list of strings, and just write them out line by line, as XML comment structure allows it. Also change config from Properties to Map<String, Object> and now it is possible to configure List<String> for license.
