These are the same as above, except that the messages sent
 are also sent to all other plugins and Metamod plugins.
This means that if you send one of these messages, other plugins will
 be notified, which was previously impossible.
BE CAREFUL! Using these incorrectly, or not for their intended purpose,
 could cause infinite recursion or something just as bad.
NOTE! These natives are experimental.
