Tonight's Photobomb Feature(s): Pictures Dir View (and layout and better ink)

The main feature that I implemented was that your pictures directory gets scanned, and all the pictures get added as buttons ready to be clicked. Clicking the button adds the pictures to the goocanvas.

I spent a few minutes creating an annotations toolbar (though just noticed I did not move the color button to it).

Also, I changed the data string for the ink paths to use bezier curves instead of just being lines. This makes the ink a little nice.
