Added note to documentation about placeholders not working in IE7.

As per issue: #2417

I don't feel this is something we need to put into the BS docs. If we went down this route, we'd set precedence for adding notes about compatibility for everything. This is different than the progress bars component, which doesn't work exactly the same in every browser, because it's a custom component we made from scratch. Placeholder is a browser feature.

Fair enough Mark.

I just think it would catch a number of people by surprise when they create forms with just placeholder labels and in IE it's completely useless.

Thanks for a the work, loving Bootstrap 2.

For anyone stumbling on to this pull request, the placeholder attribute does not work in IE9 either. There's a janky workaround using Modernizr, though.

I would recommend github.com/jamesallardice/Placeholders.js, doesnt require jQuery and supports IE6+ along with a few other browsers. It doesn't kick in unless needed. Also, can be used with modernizer and a loader like this:

// HTML5 Placeholder Attribute Test
if (!Modernizr.input.placeholder) {
  require(['placeholders'],function() {
    Placeholders.init()
  })
}
