eBay's TSV Utilities repository renamed

[Jon Degenhardt]

I've renamed the TSV Utilities Github repository from 
eBay/tsv-utils-dlang to eBay/tsv-utils. This is to better reflect 
the functional nature of the tools.

Links pointing to the old github repo will be redirected to the 
new repo. This includes git operations like clone, etc., so 
Project Tester should not be affected. Let me know if any issues 
surface.
