-KinematicBody2D::move now properly recognizes collision exceptions and masks, fixes#1649
-Removed object type masking for KinematicBody2D
-Added a test_motion() function to RigidBody2D, allowing simlar behavior to KinematicBody2D::move there.
-=-=-=-=-=-=-=-=
-Changed material unshaded property for an enum, which supports light-only shading
-Added a "Mix" shading mode, useful for using lights as masks
-Added energy parameter to Light2D
-=-==-=-=-=-=-=-
-Small fixes in canvas item light shader
-Fixed compilation in server target
-Export for Android makes 32 bits display as default
-changed version to 1.1beta1
-input now correctly works when using viewport scaling
-added function to get areas/bodies in given point
-added function to get space state directly from world
Added support for 2D shadow casters.
*DANGER* Shaders in CanvasItem CHANGED, if you are using shader in a
CanvasItem and pull this, you will lose them. Shaders now work through a
2D material system similar to 3D. If you don't want to lose the 2D
shader code, save the shader as a .shd, then create a material in
CanvasItem and re-assign the shader.
I could reproduce the crash described in #1284 only with 32bits versions of godot.
The test scene contains a Plane collision shape, and a kinematicsbody with a Sphere collision shape.
The crash occurs into `CollisionSolverSW::solve_distance_plane()` on line 299 when `p_shape_A` is a `PlaneShapeSW` object and when `p_shape_B` is a `MotionShapeSW` object, because `int support_count;` is not initialized by default, and because `MotionShapeSW::get_supports()` does not change `support_count` once passed as referenced parameter, and if the default value of `support_count` is greater than the length of `supports[16]`.
I don't know if it is the good way to fix it because i'm not skilled ennough with the physics server inner working, but this fix prevents the crash and the test-scene seems to work correctly.
