Log:
  lualoader: Simplify menu definitions a little further
  
  Allow "name" entries to be simple strings, instead of just functions. We
  know whether we support colors or not by the time any of this is setup, so
  all menu names that are basically static with colors sprinkled in are good
  candidates for simplification.
  
  Also simplify "func" in many cases where it's just invoking another function
  with no arguments. The downside to this simplification is that the functions
  called can no longer be trivially replaced by a local module. The upside is
  that it removes another layer of indirection that we likely don't need.
  
  These can be re-evaluated later if a compelling argument is raised, on a
  case-by-case basis, for replacement.
