LPS-33698 - cssClassName inconsistent with Taglib naming scheme for cssClass private property

Hey Sergio,

I wanted to send this pull request to you to review since we were trying to figure out why for this taglib, the cssClass was named as cssClassName?  The ticket to update this issue can be found at http://issues.liferay.com/browse/LPS-33698.

Please let me know if you have any questions.

Thanks!
