Various SSL code fixes and improvements

The skeleton config is now wrapped (again) within 80 columns, as it should be.
Instead of declaring multiple variables, we declare one object (Nssl) and use it everywhere else.
Make the new configuration variables optional.
Use the old SSL proxy if camo has not been configured

Also included some fixes to the skeleton and the setup README.
