Subject: * 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
