copyFileFromNode can truncate file names

[rjanik114]

It's been observed that in some cases, file names have been truncated after files being moved with the copy functions. There's no manipulation with the file names in Sunstone, but apparently, tar used to truncate file names in older systems. We need to find a way to work around this. Users of these methods don't necessarily expect that the methods will tar the files prior to copying them.
