Better handling of 0 width Chosen

[utkant]

I am not sure why this is but I guess it is because it cannot be calculated its width. I therefore suggest it to be set to 100%(or not set at all) instead, so that it shows up when shown. If the function container_width could be changed to this:

AbstractChosen.prototype.container_width = function() {
  if (this.options.width != null) {
    return this.options.width;
  } else {
      if (this.form_field.offsetWidth == 0) {
          return '100%';
      } else {
          return "" + this.form_field.offsetWidth + "px";
      }
  }
};

I think that would make alot of people happy. I made that change and it helped me...

I would like to see Chosen default to 100% or auto width instead of 0 widths. This should also be accompanied by a console.warn/log message that says why a default was used. We see this issue far too often!

We should possibly also consider the element's width style property if it's set.

Oh man this issue is sooooooo old. I think there's enough open width things (including my old, old pull #1439) that it's probably not necessary to keep it open.
