generated zipfile contents do not have file permissions set

More specifically, on OSX/Linux the permissions are 000.

Example:

% curl https://startsteeltoe.cfapps.io/starter.zip > foo.zip
% unzip foo.zip
Archive:  foo.zip
  inflating: Dockerfile
  inflating: Program.cs
  inflating: steeltoeProject.csproj
