Make the Character counter great again

[fcolarich]

The character counter uses the limit of the chat input that is 250 chars to color its bar, but the chat input has a 5 line limit, which means only 155 characters fit into its 5 lines, OR 25 emotes in 2 lines.
Which either way looks bad.
So I propose we use both the line amount and the character amount as limits to color the character counter, each line coloring either 20% of the value OR the amount of chars that fit into it (if they are emotes). This way we always show a "real" limit.
