Add ability to add a custom Class to a view

[MikeAntill41553]

It would be great to have the ability within the view settings to add an additional Class for CSS. Currently this can be done by using the view#s, but if you have a number of elements (for ex a Form) that need formatting within a view, this requires several lines of CSS. If you have a number of views (ex Forms) that you want formatted the same way, you have to add all of these elements for each form. This can also be accomplished by attaching a handler to the view to add the Class, but the performance isn't good enough. The lazyloading of the javascript causes the view to come up looking like a standard knack view then 1-2 seconds later switches to the customized look.
