These changes are intended to allow the MESS software list items to be saved as files instead of zip archives. The reasoning behind this is to allow users with compressed volumes to avoid having to take the performance hit of compressing everything twice - or having to convert all their xml based .dat files to clrmamepro .dat file format to take advantage of the 'forcezipping no' tag. These changes were made with the code from DatXmlReader.cs as a model.
