HTML4/5 Tag support

[belisoful]

There are a whole host of HTML Tags that are not yet in PRADO.

I am specifically thinking of some HTML4/5 specific tags:

• Dialog <dialog> is needed for better "modal div" support. Some JS may be needed for a dialog for an option if clicking outside the modal closes the modal. also <form method="dialog">?
• Canvas?
• Embed?
• Main tag
• Nav tag
• Section tag
• Menu tag
• Code tag (Samp, var, and kbd)?
• Output tag?
• Meter tag?
• Progress tag. Progress tags could also be active.
• Samp
• SVG tag?
• video?
• audio?
• template tag. This should be two tags, one is the HTML Template, and the other is an instance of that template and/or a reference to that template in Javascript.

I'm also looking at <form method="dialog"> in dialog tags. Should this be supported?

The reason why these primary tags should be supported as PRADO tags is for Skinning purposes.

Also <input type=color> supersedes our color picker. type=time and type=date are also in html

Also, we might want to look at "Web Components" as a way to universalize PRADO web side components. I'm not sure how the tech would fit with PRADO and its JS, but it's something to consider.
