Title: Respect config options constrain/constrainHeader

The dragging behaviour of instances of `Ext.window.Window`
usually can be configured with e.g. `constrain` or `constrainHeader`.

Since our `gx_popups` usually start pinned to a location and get their
dragging behaviour added when they are unpinned, those config options need
to be passed to our dynamically created dd-object.

The `GeoExt.window.Popup`-tests pass in FF 17.0.1, Chrome 23 (both on a linux box) and Internet Explorer 8 (Win XP). The example is functional in those browsers.

Please review.
