Ticket 48386 - Clean up dsktune code
    
    Bug Description:  dsktune is old, and has old formatting. This cleans
    many aspects of the code base, from whitespace to bracing.
    
    Fix Description:  2 space to 4 space.
    Braces on all if statements.
    
    NO CHANGES to program logic have occured. Only formatting.
