Listing directories now fully operational.

- Synthesize and return the root folder
- Assign unique inodes to each file
- Actually return the children of each node, not the current node  :)
- Return the right type from Lookup()
- Include sizes for files
- Include the associated account's email address in the volume name
- Warn if calling Read() -- it doesn't work yet, then comment it out entirely
- Warn if we can't find the parent of a file (ignoring this error caused me
  some trouble, in not noticing the root file wasn't returned by the API)
