Revert "deleted unnecessary project files from AddOrUpdateContact demo project"

This reverts commit e48bab89b04d28eaab03d3a0a42fcdb347ec5d6a.
Added libraries to Eclipse classpath
Added "Status" Parameter for getContacts()

getContacts() method.
This status allows Contacts to be fetched by their active states, those
of which are defined by the API as:
< ACTIVE | UNCONFIRMED | OPTOUT | REMOVED >
