2.5 - Action Editor / Dopesheet

Initial commit of drawing code for Action Editor / Dopesheet. By default, the Dopesheet is now enabled (like in AnimSys2). There are still a few unresolved problems (like bad alpha blending for icons, and keyframes still not being drawn). However, these will be resolved in due course.
