Specifing the lifetime for retreving the credential at Gridsphere

Currently, you could not set the value of the lifetime for retreving the credential at gridportlets.

To do, you have to re-compile and re-deploy the gridportlets.

at gridportlets directory,

$ vi ./src/org/gridlab/gridsphere/services/security/gss/impl/CredentialRetrievalServiceImpl.java

By default, RETRIEVE_LIFETIME is 8000 seconds.
You can specify the lifetime for retreving the credential by changing the value.
and then,

$ ant install
