bugfix: The Frenzy special power no longer reveals the target location

[Stubbjax]

Summary

This change removes the location-revealing effect from the Frenzy special power of all Chinas.

Details

Frenzy's behaviour now matches Emergency Repair and GPS Scrambler, achieving behavioural consistency between all support powers as a result.

It is worth noting that the opponent can still observe any applicable particle or audio effects at the target location both before and after this change.

Rationale

This is a balance concern due to the fact that China Infantry General gets access to Frenzy at Rank 1, which grants it a strategic advantage over the other China factions at the start of the game when used to scout the opponent. This needlessly tips the scales in Infantry General's favour despite it already being the better army.

Only destructive powers - where the user may want to observe the resulting outcome - should reveal the target location. There is no logical reason to design a support power - that can only affect allied (and thus visible) units - with the ability to reveal the target location.

The game's design language becomes cleaner and easier to understand as a result, with fewer, more concrete rules:

• Destructive power: Reveals target location
• Support power: Does not reveal target location

Testing

Below is a comparison highlighting the newly achieved consistency between Emergency Repair and Frenzy:
