* Player character now experiences acceleration and friction when walking around the map! * Actor position and movement had to be converted from int's (render.Point) to float64's to support fine-grained acceleration steps. * Added "physics" package and physics.Vector to be a float64 counterpart for render.Point. Vector is used for uix.Actor.Position() for the sake of movement math. Vector is flattened back to a render.Point for collision purposes, since the levels and hitboxes are pixel-bound. * Refactor the uix.Actor to no longer extend the doodads.Drawing (so it can have a Position that's a Vector instead of a Point). This broke some code that expected `.Doodad` to directly reference the Drawing.Doodad: now you had to refer to it as `a.Drawing.Doodad` which was ugly. Added convenience method .Doodad() for a shortcut. * Moved functions like GetBoundingRect() from doodads package to collision, where it uses its own slimmer Actor interface for just the relevant methods it needs.
