NHLView for PC 6.7.2203.13

Another small update to NHLView for PC. This release corrects the loading of NHL 2002 rosters in read-only mode after it broke in the previous release. NHL 2003 roster loading (also read-only) is now supported as well. New feature includes the ability to do column sum, average, minimum and maximum on View Rosters tab.

NOTE: Earlier today, version 6.7.2203.12 was published. It contained a bug where player numbers could not be modified in the Line Editor. Version 6.7.2203.13 fixes this issue.
