Removes topic limiter.

Topics are no longer limited to once per 2ds per client.

This massively improves responsiveness by no dropping clicks when trying to browse thru menus.

Anything that could cause lag or otherwise be limited should do that in its own topic, not blog down the rest

Please let me know if you can think of anything that should be limited in this PR otherwise, i say we find out by field testing.
