Patch 1.5.1 — Stellar Sovereigns Steam update #1006685

Added interaction to colonial events: Most event's duration can be effected like increasing the duration of positive or decreasing of negative events by spending money on them. Events now also displayed in the colony menu, and a plus or minus button appears beside them if the player has the ability to effect its duration. The cost of the action is based of the severity of the event. Also fixed an issue where you could not use variants to construct new defences and stations.
