Refactor icefaces3-users-portlet so that it uses the newer ACE components and supports portrait image upload

• Resolution: Fixed
• Affects Version/s: liferay-faces-3.0.1-ga2, liferay-faces-3.1.1-ga2
• Fix Version/s: liferay-faces-3.0.2-ga3, liferay-faces-3.1.2-ga3

• Labels: None

This task involves not only refactoring the XHTML, but also refactoring the UsersBackingBean.java class so that it has simple action listener methods like this:

public void someActionListener(ActionEvent actionEvent) {
...
}

Rather than having protected classes that implement the ActionListener interface.

UI Component Changes:

1) Use ace:pushButton component rather than aui-cc:button. Note that the reason why aui-cc:button was used in the first place, is that the demo was developed prior to the ace:pushButton component being available in ICEfaces 3.1.

2) Switch from ice:dataTable to ace:dataTable with the new way of doing sorting and filtering.

3) Support upload of the Liferay portrait image.
