Add copy/paste/duplicate in remote explorer

[boulayo]

I usually use Aptana to browse an FTP folder and save files directly to it. In Aptana, the equivalent of SFTP's remote explorer allows you to right-click on a file or folder and copy/paste or duplicate it—just like in a regular file explorer. The new file is automatically saved in the FTP folder. I actually use this feature very often.

VS Code's SFTP extension doesn't have this feature, and this is really the only thing currently preventing me from switching away from Aptana. It would be awesome if someone could implement this!
