0.2c bug fixe

- Fixed: All fleets that will be part of the attack will be set to "Attack mode" when launching the attack

Fixe: Combat duration time based on higher fleet defense
Fixe: Activity window issue in listing activities some times
Fixe: When building ship in planet, automatic scroll to top
