* Applied Gerhard's Meshing patch (Thanks! Gerhard)

* Addition of Gerhard's ZeroMesher.
* Addition of meshing OpenSim.ini parameter
* Some modifications to the Meshmerizer
* Meshmerizer set to default meshing plugin because ZeroMesher needs a memory locking fix.  We'll switch it back after the memory locking issue is resolved.

+ * This is the zero mesher.

+ * Whatever you want him to mesh, he can't, telling you that by responding with a null pointer.

+ * Effectivly this is for switching off meshing and for testing as each physics machine should deal 

+ * with the null pointer situation.

+ * But it's also a convenience thing, as physics machines can rely on having a mesher in any situation, even 

+ * if it's a dump one like this.

+ * Note, that this mesher is *not* living in a module but in the manager itself, so

+ * it's always availabe and thus the default in case of configuration errors
