Fix problem with --dsobject
Fix problem with --dsobject

Ran mcxToProfile using --dsobject but it failed with traceback:

```
./mcxToProfile.py --dsobject /LDAPv3/ldap/ComputerGroups/cgroup --identifier fubar
Traceback (most recent call last):
  File "./mcxToProfile.py", line 467, in <module>
    main()
  File "./mcxToProfile.py", line 424, in main
    if manage == 'Often':
UnboundLocalError: local variable 'manage' referenced before assignment
```

Initialized manage variable to work around. Not sure if this catches all the edge cases that the `manage` variable works with, though. :)
