Milestone Safari Compatibility

This milestone will be used to group tickets relative to the compatibility of FCKeditor with Safari. Once we'll announce the compatibility, the milestone will not anymore exist, and all Safari bugs will be moved to the normal tickets system.

We are working together with the developers of Safari's core software, named WebKit, to fix both sides. It means that not only FCKeditor must be fixed, but also Safari needs fixes to be able to work properly.
