Fresh 1.4.0 tarball added

It recently came to our attention that our 1.4.0 release was packaged in a way that caused problems when unpacking the tarball on certain platforms, such as newer Macs. This afternoon we refreshed the release download with a copy that should fix the issue. We apologize for any frustration or inconvenience that users may have experienced. Thanks to those who brought the issue to our attention and sorry not to have caught it earlier.
