Subject: Fix interpretation of physics mesh proxies from mesh data

As per http://wiki.secondlife.com/wiki/Mesh/Mesh_Asset_Format, some submesh blocks may just have the flag "NoGeometry" to signal that they provide no mesh data.
If a block contains this, ignore it for meshing purposes rather than suffer a ClassCastException
This fixes physics proxy meshing, so you can now walk through mesh doorways, properly stand on the trailer of mesh trucks, etc.
To get mesh physics proxy, the UseMeshiesPhysicsMesh must be true in a [Mesh] config section in OpenSim.ini (example in OpenSimDefaults.ini).
Convex hull physics not currently supported.

Subject: When loading library asset set, only store an asset if it's different
 from an existing one with the same id.

We compare existing and loaded asset by doing an SHA1 on both, so that a changed library asset will still update the store.
This cuts asset library load time from 10 seconds to <1 sec.
Note, a fix on the previous commit revealed a bug where a library script cannot be copied except on the first login after a cache clear.
This is unrelated to this commit and needs to be fixed at some subsequent time.
