respond to Dbghelp.SymGetTypeFromName correctly

[pancelor]

I think this is partially why necrolua.get was failing (#5)

I'm not sure why Dbghelp.SymFromName is failing, but I'm pretty sure it is

Update:

I have git checked out to d994e81, and I rebuilt necrolua.

This is my mod:

necrolua.hook("c_Player::p_UseBomb", function(func, self)
  print "c_Player::p_UseBomb"

  print "inside mod 1"
  local cls = necrolua.get("c_Enemy")
  print "inside mod 2"
  local obj = cls:m_GetRandomEnemy()
  print "inside mod 3"
end)

When the game loads, I press the bomb button and the game crashes:

Any idea what's happening here? Notice that nl_symbol("c_Player::p_UseBomb") and nl_type("c_Player") get called early on in the log output, and they succeed, but calling nl_symbol("c_Enemy") later results in Error 126: The specified module could not be found. ??

hmm, changing necrolua.get("c_Enemy") to necrolua.type("c_Enemy") makes this error go away. That makes some sense I guess? Error 126: The specified module could not be found. was very confusing though.

I guess I don't understand exactly how to use necrolua.get
