Subject: [PATCH] [CSE] Display menu for encrytp / decryot folders

If the server supports client syde encryption, display
a menu on right click that should display encrypt and decrypt.
ideally it would show the encrypt if the folder is decrypted, and
decrypt if the folder is encrypted but currently there's no way
for the client to know that.
