Login form double submit

[Scott Cantor]

I vaguely thought the default view had some Javascript in it to prevent this, but all it does is rename the button to try and discourage it, so my memory must be faulty. I checked my pre-retirement files and no difference.

If somebody knows how to do it and donates a patch, I will commit it. Nothing would be bulletproof, but something that disables the button somehow added to the existing onClick function is probably the closest.

The iPad's handling of the keyboard with web sites is truly abysmal, speaking as an iPad user.
