v0.7.9

New features:

• Moves use independent cooldown time now.
• There will be an internal cooldown(10 ticks, 0.5s) when switching the moves and the move's cooldown is lower than 10 ticks.
• The cooldown of moves with a charging turn(Solar Beam) or moves that require recharging(Hyper Beam) will be doubled.

Bug Fixes:

• Fix the bug that the arrow_projectile might cause a crash
• Fix the bug that the melee attack and range attack can't change fluently.
