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: The grep way wasn't really working. Now using CLI app I made ( TNT - Trailing Nulls Trimmer) instead. Also restores files as sparse...
