V6r11 fix rms 141125

1. Test existence of job in finalization: if absent, terminate OK
2. Allow that permissions are OK for part of a list of LFNs (when testing write access to parent directory). Allows removal of replicas even if one cannot be removed
3. Test SE validity before removing replica
4. Typo fixed in ProxyManager
5. Fix request timeout computation
6. Fail requests for users who are no longer in the system
There is a nice Core.Utilities.PrettyPrint.printTable utility for this kind of output. Please, use it
