Talents re-balanced

It makes the difficulty progression of the game more balanced by changing the talent point gained per level.

Compared to the vanilla, the difficulty at the beginning is almost the same until ~lvl 15

then the difficulty increased progressively until ~lvl 35,

then it's reaching progressively the original balance to lvl 50.

This way, balance is better through the all game.

See picture for seeing the talent points table.

The total of points gained is the same as the vanilla one.
