Add ability to render part of a local history window. 

This is achieved through new function history_redraw_rectangle.
It takes the co-ordinates of the history area to plot as parameters 2-5
and the co-ordinates of the top-left position to draw this area as params 6,7

Added local history scrolling to Amiga port using the above function.
