Title: Add Shaded Polygon to LineProfile Plugin Output

This addresses #865. The output now contains a gray polygon with the same shape as the overlay region shown by the tool. I also caught a bug when the line endpoints were floats (`draw.line` did not like them), so I converted the points to integers (see line 171). I tested this with all four line orientations (hence the check on line 163). I am using a 32 bit install of Anaconda 2.7 on Ubuntu 12.04.
