Allow other named NetPermissions to be used

Summary

Allow other named NetPermissions to be used.

Problem

The current specification of java.net.NetPermission states: "The following table lists all the possible NetPermission target names ...", which implies that unless the permission target is listed in the table, it cannot be used.

However, there is no such enforcement in the implementation, and it is useful and somewhat common for applications / libraries to create their own permission target names.

Solution

Relax the specification so that non-listed permissions are allowable. The table will remain, but will only document Java SE permissions.
