[Dillo-dev] fullwindow_start=YES config doesn't work with 2.2

When dillorc's fullwindow_start=YES (which is supposed to hide the widget panels on startup), it doesn't actually do this. (It does hide it after you click on a link or type in a url.) My guess is it was assumed that the first thing you want to do when opening a browser is to type in a url (or click a bookmark link, etc) -- but this is not true. (Many times I want to simply load a single page and then close it.)
