Minie v0.5.0

Minie moved from the Jme3-utilities Project to a new GitHub repo.

Notable features added:

• Added single-ended versions of all 6 PhysicsJoint types.
• Added optional heuristics for configuring the center, shape, and mass of a PhysicsLink.
• Added 4 methods for compatibility with the jme3-bullet library.
• Cache and re-use debug meshes.
• Added an enable flag and a breaking impulse threshold to every PhysicsJoint object.
• Added an MhGame model for use by TestDac.
• Added SeJointDemo, TestLargeMesh and TestRectangularSolid applications.
• Added a HullCollisionShape constructor based on RectangularSolid.
• Added MultiSphere constructors based on BoundingSphere and RectangularSolid.

Other important changes:

• Debug-mesh properties are now per-collision object, instead of per-shape.
• In the example model tunings, configure masses based on density.
• In BulletJointDebugControl, visualize the A and B ends of each joint in distinct colors.
• Moved 10 assertion-based tests to the library's "test" source set.
• Fixed a bug in the TestDac application where controls were not removed for certain models.
• Fixed a bug in BulletVehicleDebugControl where odd-numbered wheels were never updated.
• Updated the native libraries to version 1.0.18 of jme3-bullet-native.
• Based on version 2.14 of the jme3-utilities-heart library.
