[request] enhance the list output to show the base64 decoded file names

[BertLindeman]

Using spike-tools for a few hours now.

• Looking at the list output first.
  The slot file name on my hub is base64 encoded.
  As an example:
  Name: ZGlyZWN0b3J5X2xpc3Q=
  Name decoded: directory_list

• Looking at the list output with --debug I see a fields that are not printed

  • project-id - not base64 encoded but I do not understand it
  • id - some number that I also do not understand
  • type - in my case always python, but I have only one hub....

suggestions:

1. Add a line to the list output (at most 20 lines, so only few) with the decoded file name
2. remove id from the print and add type
   unless you have an explanation what it means.
3. Add the project if we know what type of encoding there is on it

Something like this maybe:

#	Name / Name decoded	Size	type	Last Modified

If you want a pull request for this I will make one, of course.
