Added the unique skill "Wide Dance"

The unique skill "Wide Dance" has been added to Lene. Holders of this skill will grant another action to all units in 4 squares around them that are targetable by the Dance when using the Dance command.

This skill replicates the performance of the FE4 Dance. The name of the skill is a reference to Etrian Odyssey 4.

It is not made to dance immediately when the Dance command is selected as in FE4. I thought it would be more convenient to look at the information of the target unit and can choose whether it really dances or not, I left it the same as the traditional operation of the Dance command.

Units whose class is Dancer or Master Dancer cannot be the target of the Dance command and will not be granted another action under the effect of this skill.
