Switching IceFaces from 1.5.3 to 1.6.0

From Foochal

Here are a list of problems that I faced:

• Tomcat version: You need to use at least version 5.5 of tomcat
• apache commons-fileupload should be version 1.2
• Update theme names which were customized: http://support.icesoft.com/jive/servlet/KbServlet/download/751-102-946/ICEfaces1_6CSSClassNameChanges.htm
• I had to change outputStyle from:

<ice:outputStyle
     href="#{facesContext.externalContext.requestContextPath}/css/ecommendation.css" />

to

<ice:outputStyle href="/css/ecommendation.css" />
