Significant rewrite of maximbaz's clipboard tool

Currently this adds file object and descriptions separated by a control
delim, rather than raw clipboard text, fixes some issues with invalidly
rendered null terminated clipped objects.

I am also working on a delete function that uses fzf --bind method and
the reload function. This is currently not working for some unknown
issue. I'm working on resolving this issue.
