[New Feature] Trigger action for giving credits to a house

[Rampastring]

Description:

Tiberian Sun doesn't have a trigger action for giving credits (money) to a house. CnCNet ts-patches adds one.

CnCNet ts-patches implementation: https://github.com/CnCNet/ts-patches/blob/master/src/trigger_actions_extended.asm#L94

The ts-patches implementation has a bug that, while the trigger action works for multiplayer houses (that normally cannot be used in any triggers in vanilla TS), it doesn't work for singleplayer houses.
