Make NetworkVar show their name for cl_showerror

I know NW2 variables can do this.

NetworkVars (https://wiki.garrysmod.com/page/Entity/NetworkVar) are defined entirely in Lua so this would be quite difficult to do without redoing the whole system in C++.

Couldn't you just implement a simple idx->string array on the C++ side for the sole purpose of console print? You can send in the string from Lua when NetworkVar gets called, and have some dummy internal function like ent:SetDTName(idx, name). Maybe there's a better solution.
