Version 2.0

• New function: entityMapID( number id )
  Returns entity that has given MapCreationID. Unlike entity(), it will always be the same on same map, no matter how much you clean up or restart it.
  
• New function: Entity:getMapID()
  Returns an entity's map creation ID.
  
• Entity:fire() and Entity:setKeyValue() now return 1 on success and 0 on failure.
  
• Overall code improvements.

Version 1.2

- Added new function Entity:setKeyValue that allows you to set a keyvalue / spawnflags for an entity. Useful for developers, please check the Valve Developer Wiki for lists of possible values.

Version 1.1

- Added support for Prop Protection addons. The function now calls the hook "CanProperty" to check if a player is allowed to manipulate an entity.

- Removed IsOwner() check, because it's unreliable and it's the job of a prop protection addon to restrict things. If you don't have one, please get one if you want to restrict the usage of this addon.

- Added convar "wire_expression2_entfire_norestriction". If set to 1, it allows all players to manipulate all entities in multiplayer.

- Toned down error message: They now print to chat and no longer break the E2.
