gitk includes many user defined configuration variables, has all of these are listed in $config_variables. But this list is not used to define the variables to be loaded, saved, or restored when cancelling the configuration dialog, and developers must maintain separate lists of variables for these purposes. This leads to unnecessary errors and merge conflicts. Let's replace those separate lists with $config_variables to make maintenance easier. While we are on topic, sort the list of names in $config_variables. This makes it simpler to scan and has fewer chances of conflicts when new names are introduced.
