PixelPaint: Allow drawing line between 2 points with BrushTool

Browse source 
Sometimes you want to draw a straight line between 2 points, but
using the nice-looking brush we have instead of the hard line we
would get using the LineTool.

This patch adds the ability to click somewhere with the brush, and
then Shift+click somewhere else to draw a line between the two
points using the brush stroke. Seems like an obvious addition
considering we already have a helper function to draw lines :^)
