In addition to the environment folders, graphical templates can be read from the XS_FIRM and XS_PROJECT folders. Previously, the \template folder was excluded from the template file search if it was a subfolder of  XS_FIRM or XS_PROJECT. Now, the XS_FIRM\template and XS_PROJECT\template folders are included in the template file search. Drawing templates are searched from all XS_PROJECT and XS_FIRM folders, except for the hard coded folders like Organizer, or hard coded template folder subfolders.
