Add hero abilities with inversion

[tdauth]

First add inversion of hero XP, hero level ups, getting skill points and hero skills. Can we actually unlearn hero abilities or at least change their level?

Protagonist:

• Disarm: Hostile unit cannot attack for some time.
• Close combat: Hits a number of units in close combat.
• Speed run: Increases the movement and attack speed of the Protagonist
• Ulti - The Protagonist - everyone has to act according to the Protagonist's plan. Takes over the control of several units for certain time. Inverted effect. The units are simply restored and change the owner?

Neil:

• Lock/unlock doors - Should work on destructable gates to close or open them.
• Driver - When he is in a vehicle, the vehicle moves much faster and has more defense?
• Medic - Heals units around him.
• Ulti - Cavalry - Calls soldiers from the future. Inverted: invert the timed life effect backwards.

Ives:

• Commander - Command aura.
• Information - Gets information from the blue team about how things will turn out.
• Soldier - passive effect which increases armor, attack rate etc.
• Ulti - Artillery Strike: Calls in an artillery strike.

Volkov:

• Booby trap: Creates a massive booby trap.
• Headshot: Kills a unit with a fatal head shot.
• Instructions: Gets instructions from Sator. Increases attack speed etc.
• Ulti - Gold bars: Gets gold bars from the future
