PCD Version 1.1.0 has been released

This is a major release with many updates:
- Using standard system types defined in sys/types.h.
- Updated STATUS to PCD_status_e and IPC_status_e respectively.
- Support crash-daemon only mode (no rule files, acts only as a crash daemon).
- Support x64 platforms (great for running pcd on your Linux PC development machine).
- pcd now kills all its children when terminating and daemonizing in the beginning (no need for running explicitly in the background with &).
