Yay! New version!

Major new features:

• PH_FIXED joints
• support of NxJoint* pointers in Lite-C, so that you can store and pass them instead of using the entity - this is required from now on, if you establish more than one joint per entity. Of course, there are legacy functions that work always on the first joint; and all GS functions were modified to this behavior
• you can set the default number of iterations globally via pXSetDefaultSolverIterationCount
• typed access to joints (e.g. "give me the second ball joint of the my entity") and various helper functions
• fixed a memory leak when calling pXcon_add more than once on entities

changelog:

• bugfix: the userData member of actors wasn't resetted to NULL, so, it was not possible to detect if an actor already has an associated JointUserData object or not
• change: the functions pXconGetLimits, pXconGetAxis were changed, so that they work as described for the first joint
• change: pXconGetPrismaticLimits works now for the -first- prismatic (!) joint
• change: pXconGetType returns the type of the first joint, otherwise PH_WHEEL if it is a wheel, otherwise 0 if it has no constraints at all, otherwise -1 if it has no joints, but wheels, otherwise -2 when an error occurs
• new: pXconGetJointLimits returns the limits of a joint
• new: pXconGetJointType returns the type of a joint
• new: pXconGetJointAxis returns the axis of a joint
• new: pXconGetTypedJoint... returns the joint with a given type by index, first, or last
• new: pXconNumTypedJoints returns the number of joints of a given type, associated with an entity
• new: pXconGetPrismaticJointLimits works like pXconGetPrismaticLimits, but for a specific prismatic (!) joint
• new: pXcon_add support now the PH_FIXED joint constraint; a second entity is always required
• new: pXentGetSolverIterationCount(Ref) retrieves the number of solver iterations of an entity
• change: pXent_setiterations is deprecated now; use pXentSetSolverIterationCount instead
• new: new pX.cpp/.h for all upcoming system-related functions (internal)
• new: pXGetDefaultSolverIterationCount returns the default value for solver iterations, assigned to a new physics entity
• new: pXSetDefaultSolverIterationCount can be used to change the default value for solver iterations, assigned to new physics entities
