Add possibility to copy the results of a 'Find in project'

[ovierlinck]

The 'Find in project', with the support of file/directory pattern is great.

It would sometimes be very helpful to be able to copy to the clipboard the result of the search (the files names and matching lines)
This would support further processing of the search results, typically pasting the search results in a new text file and do gain search or sorting on them. Or to support comparison between 2 search results

Unfortunately, the search result window is not selectable. It can only be clicked to reach the hit(s).

Maybe adding a context-menu with 'copy all'? or a button next to the Collapse All / Expand All buttons?
Or support 'area selection' with the mouse or keyboard (like on normal text editor window) and 'copy' / CTRL-C?
