All action icons will be given appropriate images, a total of 84 new images are taking place of the classic icons.

NOTE: Heal crew "PSION" has been renamed to Revive Crew to seperate from the baseline Heal action, the image for this psion has been changed aswell.

Other changes:
2 drydocks have been given shading effects to give some "pop" to their appearance.
The blue station has been removed and replaced with a different  one.
The dome drydock has been retouched and shaded.

Explosion effects have been changed to a new image utilizing alpha channel for better blending over different color surfaces, the explosion is much more uniform now with more flashing effect and not so ploppy.

One of the planets have been replaced with a more earthy version of land and water, in game shading will of course change the appearance some.
