Add oc/nc counterpart for remaining methods

- added classes to retrieve extended properties
- moved WebdavUtils helper to Kotlin object
- renamed some methods to reflect property name
- adjusted nullability of attributes to better match pre-existing values
- minor refactoring
- added missing licences
- replaced client with library licence
- removed initial Dav4JVM.kt test cases
