[REQ] Add property for class from SLB2

[GoogleCodeExporter]

With SLB2 it was possible to add access to a member variable by using the 
property method. I.e.

SLB::Class<ivec4>(IVEC4_LUA_TABLE_NAME, luaProgram->slbManager())
  .constructor()
  .set("length", &ivec3::length)
  .property("x", &ivec4::x)
  .property("y", &ivec4::y)
  .property("z", &ivec4::z)
  .property("w", &ivec4::w);

I can't find what the equivalent way of doing this in SLB3 would be.
