[FEATURE]

- adds three named queries in ResourceRepository
- adds class annotations for repositories in ResourceRepository
- adds class ResourceManager with the corresponding class annotations
- adds the defined named queries in the class annotation of Resource
- adds some entity constraints in Resource for 'name' and 'path'
- corrects the implementation of the 'isNew'-method in ResourceRepository
