Move setting the node permission table for a project from the web
interface to the backend. mkproj now looks at the pcremote_ok set and makes the proper calls to grantnodetype. This reduces the amount of hardwired goo in the web interface. Still, there is a bit of hardwired stuff in mkproj. At present we do not form a relationship between a phys node type and the types we assign to the virtual nodes. Thats is, nothing says that a pcplabphys implies the right to use pcplabinet, etc. With only 3 remote phys types, I just hardwired it into mkproj calling grantnodetype with type pcplab (the class for the virtnodes) for pcplabphys. Same for pcron and pcwa, (both get pcvwa). Ultimately we need a better type system. In general the type system is pretty screwy.
