LPS-32846 - Disabled text inputs look the same as the not disabled ones in the Control Panel Theme

Hey Patrick,

Attached is an update to the toggleDisabled method that we were trying to fix. Can we optimize it to something like https://gist.github.com/natecavanaugh/5207965?

I have attached a temp commit with the changes. They are not complete yet since I don't think it works with a NodeList yet, but have a look and let me know if you have any questions.

Nate had some additional comments for this issue at https://github.com/natecavanaugh/liferay-portal/pull/1090.

This issue can be found at http://issues.liferay.com/browse/LPS-32846.

Please let me know if you have any questions.

Thanks!
