feat(rc5): update to angular rc.5

- NgaModule - module wrapper for all ng2-admin custom features
- Ng Module per page
- async components load
- menu moved (again) to a separate file (as now each module has its own route file)
- no need to import Ba* directives into the pages which have NgaModule in the import statement
