@brief User preferences dialog

Sets default display font, etc.  If you want to add some value to
settings you have to add default value to defaultSettings and set
constraints in internalSettings in Settings class. Everything can be
used in PreferencesDialog.

Classes:
 - preferences::PreferencesBaseDialog
 - preferences::PreferencesDialog
 - preferences::DefaultFontDialog
 - preferences::MapsetAccess
 - preferences::CheckListMapset
