Converted fast-import to accept standard command line parameters. 

The following command line options are now accepted before the
pack name:

  --objects=n           # replaces the object count after the pack name
  --depth=n             # delta chain depth to use (default is 10)
  --active-branches=n   # maximum number of branches to keep in memory
