    fix: miscropping strings breaking on first word
    
    When cropping strings where we'd be splitting the first word only the last
    character would be dropped. For instance...
    
    >>> uiTools.cropStr("CookieAuthFileGroupReadable", 8)
    'CookieAuthFileGroupReadabl...'
    
    rather than...
    
    >>> uiTools.cropStr("CookieAuthFileGroupReadable", 8)
    'Cooki...'
