  Log Message:
  -----------
  Added [lua] conditional tag

Also made conditions fail if they encountered a syntax or runtime error. This seems the
more logical behavior than passing.

WML conditional tags were split into their own Lua file. The one in lua/wml/object.lua
relies on local variables so was left there.
