1.5.0

New fancy graphics!

This marks a milestone in the oshu! project, as the graphics engine was the
last remnant of the initial version. The new visuals uses accelerated 2D
graphics to render antialiased shapes and translucent objects. This looks nice
but is a significant load compared to the previous wireframe graphics. All the
objects are dynamically drawn using the cairo vector graphics library.
