Centralize the variable display prefs into a new option
group class: OptionGroupVariable. It gets initialized with
a boolean that indicates if the frame specific options are
included so that this can be used in both the "frame variable"
and "target variable" commands.

Removed the global functionality from the "frame variable" 
command. Users should switch to using the "target variable"
command.
