James Patrick e79c2439f9 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.

Hello, this is the usuage menu. $0 supports the following arguments.
- deamon :: starts a process that watches the clipboard, calling on-copy on copy.
- on-copy :: saves clipped content to history folder. Dedups, and trims as well.
- menu :: clip history menu using fzf.
- list :: null terminated list that fzf populates. Need fo fzf reload.
- lock :: prevents daemon/on-clip from saving value. Use for passwords, etc.
- unlock :: like lock, but in reverse.
- preview :: the preview used by fzf. Requires clip file.
