* Didn't allow to write back attributes outside the inode block (they don't 

have a user accessable stream, but they do have a file cache).
* removed superfluous dump_inode() version; the "bfsinfo" debugger
  command is now a bit more useful as well.
* Inode::fAttributes was not initialized when it wasn't used.

(coded by axeld)
