- osc getbinaries: new command to download binaries directly from the api server

- core.get_binarylist(): add "verbose" switch that returns instances of class
  File, instead of filenames
- improve core.get_binary_file(): 
   * clean up tempfiles, 
   * set mtime, 
   * set file mask
  Function signature is changed, because I'm not aware of any user than the example
  script I once published on http://en.opensuse.org/Build_Service/osc_plugins
