Remove "doubleclick file" -> open on client

Double clicking some file on the file manager causes the client to open that file. It is extremely easy to make a mistake and open a file instead of downloading it. Also, the "Open" option on right click is misleading and confusing, you may think it will open the file in nanocore but instead it opens it on the client desktop, being extremely suspicious.

To download a file, currently, you have to right click and press "Download", in my opinion it would be easier to download with double click OR right click->download, and maybe putting "Open in client" instead of "Open" in the contextual menu. Being paranoid, you could also put a confirmation popup with a text like "This file will be opened on the client PC, not in nanocore, are you sure you want to continue?"
