Business Layer; ISFileUtilities; Functions added to retrieve, move and copy files with unique file names

The following Functions have been added to ISFileUtilities:

• CopyFileUnique
• MoveFileUnique
• GetFileNameUnique

These functions allow Scripts to move and / or copy a file or simply retrieve a unique file name which will not error if a file of the same name already exists, and will not overwrite it.

• GetFileNameUnique
• Accepts an existing file name, and will return a modified, unique, version if the specified file name already exists in the folder.
• CopyFileUnique and MoveFileUnique
• These functions will copy / move a file to another location, but if the destination file name already exists, will use GetFileNameUnique to generate a unique filename so the file can be safely copied or moved without a duplicate error, or the file being overwritten.
