Separation of folder for PZH and PZP

- Changes due to folder permission
- Directories and files are created default to mode 0644.
- Default directory of android changed to /data/data/org.webinos.app/.
- Context and authentication api have their path and will be created inside PZP directory.
- Removed zap and shake from pzp module load as it generates loading error.
- Removed context and event from PZH default services, as event is not supported any more and context is going to be reimplemented.
