Rename "Local" to "Name" when referring to variables during compilation

* Variables were previously named "Local"s because they described a
  local variable - however, this is kind of a misnomer because it
  handles globals as well. This has been changed pretty much everywhere
  when appropriate (hopefully).
* Renamed obj/names.rs to obj/reserved.rs, freeing up the "names" module
  for the new Names handle
* Renamed obj/locals.rs to obj/names.rs, see above
