Update for templates to include files from the project

[tibel]

Currently when you build Item & Project templates instead of looking at the project contents all of the files on disk will be included. Including some system files like Thumbs.db if the user has selected to view hidden files. Better would be to only include the files which are listed in the project instead of all files that are on disk.

Note: title was _Exclude "Thumbs.db" from item and project templates_
