Move some of the panels specific of the installer to the package org.opends.quicksetup.installer.ui.

Made a small change in the code of the quicksetup panels to display the "Loading" message only on those panels th
at really require it (this modifications avoids unnecessary flickering).

Update the code of the status panel to reflect the changes in terms of naming and the names of the attributes (th
e terminology has changed from synchronization to replication).

Add some of the code required to handle the ADS and some of the panels to configure replication during setup (how
ever this is not visible to the user).  The panels reflect the design made by Brian.
