Fix bug 173150: change the font panel to not show font face, and strip out font face info from the saved font.

Fix bug 188300: when the text samples have focus, return custom field editors so that we can get changeFont: notifications.
Also fix a bug where if a font was missing, subsequent font selections would not stick (should help with bug 175651).
