Add a "Copy Path" button to copy path to clipboard
Summary
Adds a button to copy the object's absolute path on the filesystem to the clipboard.
I tried to add more dynamic copying abilities, but you quickly run into having to ask the user for permissions, browser~version compatibility issues, and having to write/use a wrapper for the clipboard (see the mozilla article on it).
The button I added is something that I'd use alot - when I create/browse objects in the editor I almost always end up wanting to look at its files in the terminal, which requires the objects path.
