-/** A window that has been created by a Lua plugin and is handled entirely by that plugin
-This object needs extra care with its lifetime management:
-- It is created by Lua, so Lua expects to garbage-collect it later
-- normal cWindow objects are deleted in their ClosedByPlayer() function if the last player closes them
-To overcome this, this object overloads the Destroy functions, which doesn't let the ClosedByPlayer()
-delete the window, but rather leaves it dangling, with only Lua having the reference to it.
-Additionally, to forbid Lua from deleting this object while it is used by players, the manual bindings for
-cPlayer:OpenWindow check if the window is of this class, and if so, make a global Lua reference for this object.
-This reference needs to be unreferenced in the Destroy() function.
