copy/remove/rename ivy-actions

[Julien Cubizolles <j.cubizolles@free.fr>]

I'm a helm user who decided to give ivy a try. So far I've managed to
set it to my linking but there are still some features I've not managed
to implement.

In helm-find-files, I can easily rename/remove/copy a file. In
counsel-find-file, it isn't straightforward. I guess it's just a matter
of setting up an ivy action but I did not succeed so far. I'd rather not
go back to dired for managing files. How do you ivy/counsel users go
about this ?
