Update project template to do not use removed container nodes

When creating a new Spray project the create style, shape and spray file 
contains example definitions in comments that are not valid anymore:

// Add class mappings here. Refer to EClasses here. Don't forget to configure a
// dependency to the plugin defining the EMF metamodel in META-INF/MANIFEST.MF.
// It is required to have a genmodel for the metamodel. If the Ecore model lies 
in
// a workspace project, this project must have the Xtext nature.
//
// Example class mapping:
//   class BusinessClass icon "ecore/EClass.gif":
//     container  ( fill=yellow ) 
//     {
//       text ( )  { "<<"+eClass.name+">> " + name};
//       line ( color=black width=2)
//     }
//     behavior {
//       // Enable create feature for this class and add it to the palette 
"Shapes"
//       create into types palette "Shapes";
//     }
//
// Example association mapping:
//   class Association icon "connection16.gif"
//     connection ( ) {
//       from source;
//       to target;
//       fromText "source " + source.name
//     }
