Add button to copy output of script

[Nottt]

It'd be nice to have this feature :)

Also I think you should put some donation information in your readme

Done. The button is in the right bottom corner of the output panel

restarted my docker and I picked the change. Isn't it better to have it right upper corner? In a big screen you'd have to move the mouse all the way down to copy and the go up again.

but regardless, awesome job as always! thanks
