Enemy Gates Update

In the original version of Dark Asteroids, the enemy gates were not revealed until several weeks later. It is now earlier for the individual missions to be better interspersed and for an even better gaming experience. For this reason, I also added one new mission with a gate. During the testing, I learned how the change significantly contributes to the gaming experience.

I also enriched the lyrics in the final attack on the enemy Observatory and Factory.

I added an icon to the base with the option to turn on / off the summary of the completed mission.
