LPS-31027 - aui:tool taglib fails with cast error

Hey Shinn,

I've made changes to get the AUI tools taglib to work correctly now.  I think there are some additional changes you need to make, but this issue can be found at http://issues.liferay.com/browse/LPS-31027.

Please let me know if you have any questions.

Thanks!
