Some fixes to the game not ending properly and dead unit clearing, disabled mirana because she's being worked on, a variety of bugfixes to hero talents and scaling

## General
- Increased stat growth from +50% per level to +80% (as an example, Bane +stats at lv10/20/30/40 from 81.25/287/618.75/1075 to 115/430/945/1660
- Stats Increase talent from +25%/lvl to +35%/lvl (250% to 350% max)
## Phoenix
- Fixed Supernova not taking damage from enemies.
- Supernova attacks to kill is now 30 at all levels. Hero units deal 3 damage to the Supernova.
- Supernova cooldown from 180 to 180/170/160/150/140/130
- Reworked Shard from: "Phoenix can cast Sun Ray during Supernova" to "Phoenix can cast spells during Supernova and gains 50% spell amplification during Supernova."
## Sniper
- Headshot no longer knocks enemies back, roots them for the duration instead.
- Headshot chances over 100% now overflow and trigger another roll. If multiple Headshots proc, the damage and duration are multiplied by the amount of procs.
- Take Aim no longer sets Headshot chance to 100%, instead grants +60/70/80/90/100/110/120% Headshot Chance.
- Take Aim active attack range form 70/180 290/300/410/520/630 to 200
- Killing a hero unit with Assassinate refreshes all of Sniper's cooldowns and charges. Killing a creep unit causes the Assassinate projectile to bounce to the nearest unit, dealing 50% damage.
- +100 Attack Range talent with +50% Passive & Active Take Aim Attack Range, moved back to Lv25
## Grimstroke
- Ink Swell now Basic Dispels on cast.
- Ink Swell now always deal maximum damage and stun duration.
