Global ban protection

[nvalis]

Protection against global bans (see Chatterino implementation) by blocking further message dispatch if limits are reached (current limits). For better UX warnings should be displayed to the user stating the problem and wait time till further message can be dispatched.

Current channel limits are:

Limit	Applies to …
20 per 30 seconds	Users sending commands or messages to channels in which they do not have Moderator or Operator status
100 per 30 seconds	Users sending commands or messages to channels in which they have Moderator or Operator status

And for whispers:

Limit	Applies to …
3 per second, up to 100 per minute 40 accounts per day 160 recipients per day	Users

Also add an option to disable. Make sure the rate limits are variable, not 0.334 sec between messages but 100 Messages / 30 seconds

And adapt accordingly if user is mod or broadcaster.
