  1. KinematicBody split between new CharacterBody and PhysicsBody 

    PhysicsBody now has methods move_and_collide/test_move and needed
properties for these methods: safe margin, locked axes (3D only).

Moved collision_exceptions from StaticBody to PhysicsBody for 3D
(same as 2D, and conforms to documentation).

RigidBody doesn't have test_motion method anymore, it's now redundant
with PhysicsBody.test_move.

  2. Properties for move_and_slide and remove move_and_slide_with_snap 

    - snap property to replace move_and_slide_with_snap()
- floor_max_angle, stop_on_slope, infinite_inertia, max_slides,
up_direction properties to replace arguments from move_and_slide()
- up direction now defaults to Vector3.UP and Vector2.UP

  3. More explanatory names for RigidBody modes 

    MODE_DYNAMIC instead of MODE_RIGID
MODE_DYNAMIC_LOCKED instead of MODE_CHARACTER

No more special case for sleeping behavior for MODE_DYNAMIC_LOCKED
(MODE_CHARACTER was forcing the body not to sleep, which is redundant
with can_sleep and wasn't done in Bullet).

  4. Support for kinematic_motion in StaticBody 

    Does the same thing as simulate motion from RigidBody in Kinematic mode,
and CharacterBody (previously KinematicBody).

Added support for constant linear/angular velocity with kinematic_motion
in StaticBody, which moves the body in physics.

Updated documentation for StaticBody and CharacterBody to describe their
functionalities more accurately.

  5. Safe margin cleanup 

    Safe margin property on CharacterBody only, used as argument in
move_and_collide.

Removed kinematic_safe_margin in 3D physics server, not really useful
and now harmonized with 2D.

  6. Linear velocity cleanup 

    CharacterBody has a linear_velocity property to replace the argument in
move_and_slide.

StaticBody handles reporting linear/angular velocity correctly when
kinematic motion is used (in 3D, used in vehicle and navigation).
