Clean up the code of many examples in minor ways, fix some memory leaks, and avoid the use of dialogs where a regular toplevel works just as well.

/* Header Bar
|
|
*
|
|
* GtkHeaderBar is a container that is suitable for implementing
|
|
* window titlebars. One of its features is that it can position
|
|
* a title (and optional subtitle) centered with regard to the
|
|
* full width, regardless of variable-width content at the left
|
|
* or right.
|
|
*
|
|
* It is commonly used with gtk_window_set_titlebar()
|
