Adding RC would require updating other scripts to support it. For the
purpose of the changelog just using 4.0.4 should suffice. Might Add
support for this later.
Marking this as an RC as it will take some time for me to get all
packages out and I might need to fix various packaging related bugs.
Will mark as 4.0.4 after all packages exist, should not have application
changes between these two.
Because of Sparkle, it's now required to build dupeguru on 10.10+, but with MACOSX_DEPLOYMENT_TARGET, which we now properly set, the results properly runs on 10.8.
This requires a python that has also been compiled with MACOSX_DEPLOYMENT_TARGET=10.8
