Java Application Framework For All Source

Modified the length() methods to return 0 if the input param array or list is null.

fixed a backward compatibility issue.

- implemented Jaffa.finder.CriteriaFieldPanel class to take over Jaffa.finder.CriteriaPanelFactory.createPanel(). The xtype of this new class is finderCriteriaFieldPanel.
- Jaffa.finder.CriteriaPanelFactory.createPanel() now returns an object instantiated from finderCriteriaFieldPanel.

- make Jaffa.finder.CriteriaPanelFactory.createPanel() return config object of xtype='container' rather than an Ext.Panel instance. The treatment avoids the panel config values being overridden by defaults in the parent panel. Typically, this is a problem when metaClass is overridden by the parent panel causing confusions on applying aop rules.
- the config object is regenerated to avoid modification on the input object. This solves the problem when finder criteria class has multiple instantiations in the same screen.
