Download/upload shutdown fixes 

- Missing renamed to PendingDownload
- PendingDownload now only retries 3 times rather than 6 to dowload an
  object
- Added PendingUpload, replacing invQueueSize
- PendingUpload has both the "len" method (number of objects not
  uploaded) as well as "progress" method, which is a float from 0
  (nothing done) to 1 (all uploaded) which considers not only objects
  but also how many nodes they are uploaded to
- PendingUpload tracks when the object is successfully uploaded to the
  remote node instead of just adding an arbitrary time after they have
  been send the corresponding "inv"
- Network status tab's "Objects to be synced" shows the sum of
  PendingUpload and PendingDownload sizes
