Fieldcontain: Reset width for notext buttons

Buttons with .ui-btn-icon-notext normally have a fixed width of 1.75em.
However when putting them as inline buttons inside a .ui-field-contain,
from a certain page width on they get a width:auto, making them use the
available width on the page instead of staying at a fixed width.
This overrides the width:auto with the 1.75em again in that situation.

Popup: do not call blur if the target is the body

In IE 10 (and possibly older versions of IE) when there is a single tab open
and a popup is displayed and there is another window on the same monitor,
calling target.blur() can cause the browser to go to the background because the
body element is the targetElement.  Ensuring the element is not the body element
before calling blur() fixes this issue.
