Added the unique skill “Hit Up”

The unique skill “Hit Up” has been added to Kallion. Holders of this skill will always have an increased Hit value.

Kallion is the only unit that joins as a Social Knight in the original story (although he is a Sword Knight in this hack). While Lance Knights such as Kane and Alba can only use lances, Kallion's ability to use both sword and lance is reminiscent of dexterity. Therefore, I decided to make it an always activation, rather than a specific case.
