Remove ui.detector class

The ui.detector class was not really needed and leads to the illusion
that we provide GUI plugins. For the sake of code maintainability we
don't :-).

Rather than having GUI names equivalent to the classes they are in
(which leads to weird names like TTY.TTYUI), this patch allows to give
each GUI an arbitrary string name. GUI names remain still unchanged in
this patch, the default UI when none was configured is TTY.TTYUI.
