Remove reload parameter from notepad

[NickSto]

The reload url parameter on the notepad app is used in the "select all" and "select none" buttons. And it looks might finally be trapping some crawlers in loops (see visits from this ip).

It'd be great to remove that kludge. But it does serve a purpose (see 4ddb5ab) in the situation where a user clicks "select all", then unchecks some boxes, then decides to "select all" again. Without the reload parameter, the button goes to the same url they're currently on, so the browser won't load the page again, leaving those boxes unchecked and breaking the functionality of the "select all" button.

I think changing it to a POST request might work.
