Improved focus switching for dialogs

Widgets can now be defined as being the "focus root", i.e., the topmost
widget under which focus switching happens. Normally this is the window
root widget, but dialogs use this flag to confine focus switching
inside the dialog.

InputWidget in Overwrite mode will focus switch to the next focusable
widget when the text field becomes full.
