Shadow-ignore for tells

Commented out the line where ignored users are told "Player is ignoring
messages from you." Messages will still be blocked, but the ignored
player will not know.

This is a modern tweak to the ignore system following the upgrade that allowed the ignore list to cross accounts. Also, shadow-ignoring / shadow-banning in this manner has proven very effective on other games and social media sites.

Next step will be ignore lists affecting what a user sees from the newsglobes.
