Another Generic Space Shooter v1.13.1

these patches that come an hour after the update are getting a little too common

• fixed an issue where the acid powerup had a chance at both being 100% uptime and screwed up the other powerup slot
• fixed an issue where the mysterious missingno powerup would appear
• current powerups will now always display, regardless if the UI is being displayed
• increased micro-missile movement speed from 10 to 12

I promise I test my game
