Prioritize dialog: adding/removing multiple items, adding/removing on double clicking an item, drag-n-drop fix

Remove RC from changelog version

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.

v4.0.3

v4.0.2

Update po from code

Fix cocoa build script

It wouldn't properly find python 3.5 dylib for linking.

Added Utopic Unicorn to the list of supported Ubuntu dists

Added --arch-pkg option to package.py

Otherwise, AUR packages don't work with Arch lookalikes like Manjaro.

Updated copyright year to 2014 in Cocoa about boxes

Better late than never.
