Script Summary: Disables the Espionage button on the fleet sending page if Colonization is available
When sending fleets containing both Colony Ships and Espionage Probes to the coordinates of a non-colonized position, both the "Colonization" and "Espionage" mission buttons are available (lighted). This is a bug - the "Espionage" button shouldn't be available, since you can't spy non-colonized positions. In fact, if you select it, the "SEND FLEET" button won't work.
This script fixes the bug by making the "Espionage" button non-selectable (thus leaving only "Colonization"). In addition, it automatically selects "Colonization" as the mission for the fleet.
This is a stop-gap solution; I expect that eventually the author of Antigame will include this functionality in his script. Maybe even GameForge will fix the bug (yeah, right).
