LPS-46920 - Update DOM access (document.<portlet:namespace />fm.<portlet:namespace />title to A.one('#<portlet:namespace />title'))

Hi Nate,

With help from @marclundgren, here is an example solution for https://issues.liferay.com/browse/LPS-46920.  The changes are limited to the wiki portlet.

I used your gist as an example: https://gist.github.com/natecavanaugh/1260623, but modified it slightly so that it could be used as a getter/setter and to just get the form.

Please let me know your thoughts.

Thanks Nate!
