HtmlTags v4 support

[TDK1964]

FormBlocks do not work with v4 of HtmlTags. It spits out raw HTML instead of rendered labels and controls.

Yikes, looks like when I upgraded to RTM it broke things.

I have an issue where CourseID won't show input box. I think the FormBlock sees the ID suffix and hides it. I have to confirm though.

I tried looking at the HtmlConventionLibrary but that's way too much for me there.

I submitted a pull request to work around this issue. I don't know how to link it here.
