v0.1.0-alpha.9

Buttons submit with a bare Submit: <Button Submit>Save</Button>. One rename.

Changed (check when you update)

• Type="ButtonType..." on Button, IconButton and MenuItem is replaced by Submit, or Reset on buttons. Write <Button Submit> for <Button Type="ButtonType.Submit">, <Button Reset> for ButtonType.Reset, and drop Type="ButtonType.Button" (a button that does nothing by itself is still the default). Setting both Submit and Reset throws.
• Old markup fails to build. Type and ButtonType stay for this release, marked obsolete as errors, so every old use stops the build with error CS0619 and a message pointing to Submit. (Without them, Razor would take Type="ButtonType.Button" as a plain HTML attribute, and the browser would treat that button as a submit button.) They'll be removed in a later release.
• This also ends a false "Wrong attribute value" warning in Rider and ReSharper, which checked <Button Type="..."> against HTML's <button type>.

Fixed

• <DialogClose Reset> threw "can't set both Submit and Reset" (a DialogClose submits its close form by default); it now resets the form instead.
• The error for setting both Submit and Reset names the component used (DialogTrigger, DialogClose), not Button, and is raised while the button is loading too.
