Emotes update and additions

Updated emote expressions
Added /flip (a coin - heads or tails) (protected emote with cyan ! - so it can't be faked)
Added /roll (random number between 1 and 100) (protected emote with cyan ! - so it can't be faked)
Added more emotes
Added chat timestamps possibility, but its commented out (its easier for me to maintain it like this - hope its not a bother)
