Added option to specify custom object with a Write(string) method
as argument to kwargs['f'].
Added option to specify size and position of window when printing
to script's main window. Changed token to ':' from '~'. Removed
kwargs['w']. Wait is now 'Tn' option of kwargs['f'] where 'n'
is the time in milliseconds before returning/proceeding.
Modified option when printing to standard I/O stream(s). Minor
changes here and there.
