Skill cooldowns

Obviously some of the skills should not be usable continuously. This is where the cooldown mechanic comes into play, right?

As for now, two skills have cooldowns - the "ground stomp" action of the Mechanic, and "Rush it" action of the Rogue.

The first one is the area of effect attack that I moved from Rogue; the second one allows the Rogue to take an action after a double move. This is nice for breaking the game rules for a while, thus allowing the player to alte rthe situation on the battlefield drastically.

Long story short, the cooldown mechanic is there, and is working.
