[feature request] Click to copy

[JoeyLambs]

I'm using RDT to work on a mobile site, so I find difficult to read the server/client differences in the tool

I prefer to copy-paste them into another text editor to read.
It'd be nice if there were a faster way to copy/paste, since clicking and dragging highlights both the server text and client text together.
