Add support for the InnerText JavaScript property to browsers that do not correctly support it, such as some versions of Mozilla Firefox.

Please note: The “Try/Catch” is REQUIRED for this to work properly in some versions of Opera Browser, as Opera properly supports InnerText but attempting to query for its support will throw an error.
