Work on new player class "Archer" finished.
Now Achievements are implemented.

Ranged class, has less HP and need to stay back from frontline.

Archer has supportive E skill,
such as summon ally.
They are longer cool down than other skills.

Similarly as Swordman,
has default Q, W, and E skill,
and 3 derived skills for each.
(12 skills in total)

Archer is vulnerable, and has no move skill.
Keep safe position.

Summoned ally inherit player's items.
He can act as different role by obtained item.

Some skills can kill one target quickly.
On the other hand, others have area of effect.
Combine them to adapt different situation.

Now you can play as new class: Archer.
Achievement is not implemented because not balanced yet.

Has only 3 skill items
（Together with default 3 skills, 6 skills in total）
,and some items have no effects so do not appear.
I will add archer exclusive items to have same number as Swordman.
