When creating new project, on 3rd page, when user can select drools runtime and select version of drools to generate sample sources.
Selection of 'Generate code compatible with' should filter/depend on drools runtime selection. It makes no sense if you have drools 4.x to allow generating 5.x compatible sources.

Moreover, when user creates new project just entering project name and has as selected 4.x as default runtime. Project with 80 errors is generated.
