[LUA]: Cannot use userdata as table index

[Борис Александров <boriscool007@...>]

Example code:

" temp = {}

  temp['string'] = 'foobar'

  temp[GetPlayer(0)] = 'player'

  temp[GetEntity(0)] = 'entity'

  print(temp['string']) -- foobar

  print(temp[GetPlayer(0)]) -- nil

  print(temp[GetEntity(0)])  -- nil

  for k,v in pairs(temp) do

     print(k,v)  ----- stringfoobar

                   ------ Player(0)player

                   ------ Entity(0)entity

  end
