    Bug 345924 - Conditionally change Options dialog cancel button
    
    When the options dialog is loaded, the main buttons are a sensitive
    'Cancel' button and insensitive 'OK' and 'Apply' buttons. When changes
    are made the 'OK' and 'Apply' buttons become sensitive and when pressed
    the 'OK' button will make changes and close dialog whereas the 'Apply'
    button will make changes and the dialog will remain open but with these
    buttons insensitive leaving just 'Cancel' sensitive.
    
    This could be confusing so this commit changes conditionally the text
    label of the 'Cancel' button between 'Cancel' and 'Close'.

    Bug 345924 - Report options 'Reset Button' always flags changes
    
    If a report is loaded with default settings and the 'Reset button' is
    pressed the 'OK/Apply' buttons will be enabled which should not happen
    as there are no changes to be made.
    
    Fixed by resetting the changed flag on options load and then comparing
    the current value to the default one when the 'Reset button' pressed.
