+Add option to disable file downloads via CLI
+
+This patch adds support for a new CLI flag called `--disable-file-downloads`
+which allows a user to remove the "Download..." option that shows up when you
+right-click files in Code. The default value for this is `false`.
+
+To test this, start code-server with `--disable-file-downloads`, open editor,
+right-click on a file (not a folder) and you should **not** see the
+"Download..." option.
