Marauding gives attack bonus vs. district defenses

[Infixo]

From @mrobaczyk: Marauding gives also +7 CS vs districts. Check LOC_PROMOTION_MARAUDING_DESCRIPTION

<ModifierId>URBAN_RAIDER_BONUS</ModifierId>
<Name>Amount</Name>
<Value>7</Value>
<SubjectRequirementSetId>URBAN_RAIDER_REQUIREMENTS</SubjectRequirementSetId>
	<RequirementSetId>URBAN_RAIDER_REQUIREMENTS</RequirementSetId>
	<RequirementId>PLAYER_IS_ATTACKER_REQUIREMENTS</RequirementId>
	<RequirementId>DEFENDER_IS_OCCUPYING_DISTRICT_REQUIREMENT</RequirementId>
		<RequirementId>DEFENDER_IS_OCCUPYING_DISTRICT_REQUIREMENT</RequirementId>
		<RequirementType>REQUIREMENT_PLOT_HAS_ANY_DISTRICT</RequirementType>

Again, it has "bad" requirement for the opponent. Fix is the same - add "opponent is not a district".
