Add Ajax support for Searching entities.

For a better user experience, adding ajax support for searching entities will be appreciated.
Here are the modifications to have such support:
For example: Let's consider the entity : World.java

1- change the method public void paginate() to public void paginate(AjaxBehaviorEvent event) in WorldBean.java

2- in /world/search.xhtml : change =>

<f:event type="preRenderView" listener="#{helpBean.paginate()}" />

to =>

<f:event type="preRenderView" listener="#{helpBean.paginate(this)}" />

3- embed : <f:ajax /> in <h:inputText fields and/or <h:selecOneMenu ... components.....this way:

<h:inputText ........>
<f:ajax event="keyup" render="the_id_of_the_datatable" execute="@form" />
</h:inputText>

Remark: the ajax event for SelectOneMenu is click, not keyup.

4- finally in WorldBean.java, modify the create method, so that it becomes:

public String create() {

if (this.conversation.isTransient()) {
this.conversation.begin();
} else {
this.conversation.end();
}
return "create?faces-redirect=true";
}}}

5- Optional: remove the search button in search.xhtml
That's all.

Ideally, Forge should let the developer specify if he/she would like to generate these statements in order to enable Ajax or not. Example:

scaffold-x from World.java --enableAjax true
