Trailing Nulls Trimmer Batch package

Wanted to trim trailing nulls from a biggish partition file. Didn't find a good ready made tool for it, so I made one. Uses grep to find the last non null character and then truncates the file after it.

Updated: Now works also when the file contains only nulls. Backup notice added.
