v1.6.0

Features/changes:

• cpobj now accepts multiple source files
• deprecated homebrew. Please use pip exclusively going forward.
• changed the behavior of rmobj to be more consistent with rm:
  • rmobj -f will not prompt the user if they want to delete files/directories at all.
  • rmobj -i is now needed if you want to be asked about every delete operation. If you just pass rmobj -r you will be asked only once now.

Bugfixes:

• rmobj is now more selective about removing key prefixes. This means that rmobj -rf bucket:foo will now remove everything under bucket:foo/*, but not bucket:foobar/. Thank you to @Sanghyun-Hong for reporting this bug!
• fixed a bug in cpobj where a single key could not be copied out of the object store with a different key name locally.
• more graceful logging of S3ResponseError for multipart uploads
• implemented better error messages if invalid credentials are being used
• the exit statuses in rmobj are now consistent with the behavior for rm. The exit status will be non-zero if there were failures removing something unless -f is specified, in which case the exit status will always be zero.
