configitems: add alias support in config
Aliases define optional alternatives to existing options. For example the old
option ui.user was deprecated and replaced by ui.username. With this mechanism,
it's even possible to create an alias to an option in a different section.
Add ui.user as alias to ui.username as an example of this concept.
The old alternates principle in ui.config is removed as it was used only for
this option.
