Display the logical name of a repository in the Synchronize view

In the wake of issue #501 (closed), I have thought of having the logical name in the Synchronize view.

Currently, the title of the view is composed of the URI(s) of the project(s) being synchronized. This feature will reuse the preference defined in #501 (closed) to add the logical name as a prefix to the URI(s).

Due to Eclipse platform using the title (aka "name" or "description") in the status bar, this change will also be reflected in the status bar.
