Bug 144527 [Wizards] WizardDialog should have the maxmize button
RC6 Many of our wizards show up quite scrunched initially in High Contrast mode. When they are expanded the size is quite good. We should set the maximize flag so that we get a maximize button on the dialog shell.
bundles/org.eclipse.jface/src/org/eclipse/jface/wizard/WizardDialog.java
* it has an area at the top containing both the
 * wizard's title, description, and image; the actual wizard page
 * appears in the middle; below that is a progress indicator
 * (which is made visible if needed); and at the bottom
 * of the page is message line and a button bar containing 
 * Help, Next, Back, Finish, and Cancel buttons (or some subset).
 * </p>
 * <p>
 * Clients may subclass <code>WizardDialog</code>, although this
 * is rarely required.
 * </p>
