Bot lookback

- Bots use lookback when they have a attack item that hits back & they see you.
- Bot item throwing was made slower for easier difficulties. (Lv. 9 should still be pretty fast.)
- Bot cone detection was made much much farther & wider

Lookback sparkle is a signal for "they are contemplating throwing backwards"
