Rivals balance hotfix 2019-06-06

The June hotfix changed behavior of Kodiak and Mohawk Gunship.

Kodiak (revert)

 * Reverted the recent Kodiak changes. This unit no longer has Raider

The introduction of Raider also introduced a bug where the Kodiak was able to attack selected units when they were outside one-tile range. To fix this issue, we are removing Raider from the Kodiak.

Mohawk Gunship

 * Fixed an issue so the Mohawk Gunship Raider would fire consistently when aligning the turret to an enemy unit.

We want Raider to work smoother for the Mohawk Gunship. A slight tuning change should make this function better.
