Twitch touch-ups

I love my ratboi and he's my most played champ but even so, I cant really find a good reason to play Teitch.

Some minor adjustments I would make;

Base stats: ATTACK DAMAGE 59 (+ 3.11) -> 57 (+3) (111.87 at 18 --> 108 at 18) ATTACK SPEED: 0.679 (+ 3.38%) 0.685 (+3.33%)

Passive: Deadly Venom: True damage per second: 1/2/3/4/5 --> 2 / 4 / 6 / 8 per stack (at levels 1/6/11/16)

6~36 damage is a joke, and makes Twitch last hitting awkward. As it is, his passive basically only serves to stack E and delay recalls. Base AD reduced in compensation.

Q: Ambush Camouflage Duration: 10/11/12/13/14 -> 8/9/10/11/12 seconds Cooldown: 16 -> 18 / 17 / 16 / 15 / 14 seconds MOVESPEED: 10%, tripled to 30% while moving towards champions unseen 25% at all times

Weaker early game, similar power in mid to late game, more reliability movespeed. The window in which Twitch gained full movespeed from his Q was excessively tight owing to the large detection radius of Ambush, making it almost useless when he actually wants it.

R Spray and Pray Rat-a-Tat-Tat Cooldown: 90 seconds at all ranks 105 / 90 / 75 seconds Duration: 5 seconds at all ranks --> 5 / 6.5 / 8 seconds

Name changed back to be more appropriate for a crazy rat with a Shotgun crossbow. Now gains a lot more than an extra longsword for 5 seconds while active for ranking it up.
