Need support for History API as JsCommands

[Shabab Karim]

Hi,

I see support for page redirection(JsCommands#RedirectTo) and page reload(JsCommands#Reload). The inverse of page redirection(JsCommands#RedirectTo), something like JsCommands#RedirectBack will be very helpful. 

A possible use case is having a button on a form with a back button. At this point I am needing to bind a JsExp callback to the onclick event for the button or tell the user to use the browser back button.

The browser native History API can be used for achieving this feature.

Thanks,
Shabab Karim

You can achieve this directly using `JsRaw`: `JsRaw("window.history.back()").cmd`. You can also convert your JsExp directly to a JsCmd using `.cmd` on it, which should make it usable anywhere you'd use `RedirectTo` or `Reload`.

Thanks,

Antonio
