Secure Storage service for the gLite middleware 1.0.0-4 (Keystore Server)

Secure Storage service for the gLite middleware project provides users with a set of tools to store in a secure way and in an encrypted format confidential data (e.g. medical or financial data) on the grid storage elements.
The data stored using the tools provided will be accessible and readable only by authorized users. Moreover, it solves the insider abuse problem preventing also the administrators of the storage elements to access the c in a clear format.
The service has been designed and developed for the grid Middleware of the EGEE infrastructure, gLite, in the context of the TriGrid VL Project.
Enhancements:
- The daemon script was fixed and now verifies if another instance of the daemon is running.
- A status command was added.
- The RPM installation script was fixed: the /var/securestorage owner is now correctly assigned.
- The configuration template was fixed so that the certificate names are hostkey.pem and hostcert.pem.
