license.svn.lastchange.timestamp	Timestamp of the last commit (yyyyMMdd-HH:mm:ss)
license.svn.lastchange.date	Date of the last commit (yyyyMMdd)
license.svn.lastchange.revision	SVN revision number of the last change
license.svn.years.range	inceptionYear–lastChangeYear range, or just lastChangeYear if equal or inceptionYear is not set
