Black flash chaining update

Added:

• Added better black flash chaining

The more black flashes that hit your target, the stronger the debuffs will be (Mobs can do that too)

1 black flash - blindness and nausea

2 to 3 black flashes - nausea, slowness and longer blindness

4 and more black flashes - nausea, long blindness and total impossibility of movement

To reset the counter of black flashes that hit you, you just need to sleep

• Added debug mode (New gamerule)

Shows the maximum chance of your black flash and count of black flashes that hit you

Fixed:

• Fixed mobs didn't give debuffs or receive buffs from black flash
• Black Flash chance reducing also works on mobs now
• Fixed basic chance of black flash
