Feature request : integrate phpactor

Hi,

I've very recently discovered the phpactor tool (completion and refactoring tool) : http://phpactor.github.io/phpactor/ (edit)

There are probably several interesting features that could be used, but looking for non overlapping ones, I'd love to have "class move" and "class copy" with automatic update of namespace (and name if copy).
But maybe this has more to do with dired that php-mode ?

Sadly, I lack both the elisp knowledge and time to figure that out by myself...

Regards and thanks for all the work here !
Mikael
