Editable setup settings

Browse source 
In order to be able to change the setup settings two new setup states
are introduced `change_contrast` and `change_backlight`. All
procedures that handle the setup states are adapted to handle those
new states correct. To keep track of their values the global variables
`value_contrast` and `value_backlight` are introduced.
