Fixed:

• Insane knockback of firelancer's flamethrow.(normal edition only, didn't do against light edition)
• Poison attack can penetrate shield.
• Spearman's fire and poison particle can be seen when selected even doesn't have them

Balance changed:

• Now spearman doesn't lost special spears if melee against non effective things. Should lost when hit shielded knight?
• Assassin can dig wooden blocks faster, 6 -> 5 hits to dig.
• Musketman's shovel do 1/3 damage against logs, shouldn't?
• Now musketman can shoot bullet on discharging, then deflect up to 5 degrees. Should more?
• Firelancer's flamethrower ignites walls frequently.
• More firelancer's recoil, mass x2 -> x3.
• More quickly duelist's jab, 9 -> 8 ticks to resheath.
• Lesser duelist's digging power, 5 damage to dig wood or 3 damage to dig dirt, jab is 1 damage and slash is 2 damage.

Other changes:

• Now assassin doesn't target the blobs that have StoneStructureHit.as, such as stone door.
• Added ImportantPickup.as to acid jar, bomb box, oil bottle, fire spear and flame throwers. Also add more important score to acid jar and bomb box, like bomb arrow.
• Added setArrowHoverRect() in ArrowCommon.as to materials that kind of ammo.
  
• Firelancer's flamethrower doesn't ignite wall tiles on just shoot, for ignore self-fire.
  
• Changed firelancer's stick attack animation.
• Added crouching animation to spearman, crossbowman and weaponthrower.
• Changed spearman, weaponthrower and butcher's throwing animation, use knight's unused frame.

• Show helps more times, they are reduced after few times
• Add more value to classes common scripts to change parameter easily
• Add crouching animation to duelist, make archer's crouching shoot anim and offer to THD?
• Repairable barricade, then maybe need many changes
• Give duelist the skill that ignite water bomb?
• Give assassin the skill that change door and mine color?
• ShieldHit.as looks need to change about weaponthrower, then need to change WeaponthrowerCommon.as
