Root perm fixes, Chome debug, spaces between catalog items, and fake authors for display

[dramudit]

Various enhancements, including fixing root permissioning, allowing debugging using a local Chrome instance within the VM, spacers between items in the catalog and printing a (currently fake) list of author names along with the book titles. Will move to non-fake names once these are available in the db.

@ojongerius - I'm not sure there's much value in changing to a grep. Since this is run during provisioning, these are the possibilities:

• initial "vagrant up": the file won't exist as gradle has never run before in this VM, and will be created
• later "vagrant reload":
  • The file already exists (with or without manual changes by the user), so no action is taken
  • The file was deleted somehow, and is recreated. If the user did this as a way to disable the gradle daemon, they can instead change their config to "false" to prevent this from happening.

Ok, you have more context as I do :)
