V19 Dev/Debug - PowerAgile + Weather

This is a show-your-work/development build and contains a debug overlay.

- Woo! Should have eliminated finally the burst of speed that can come when changing movement directions. By learning better vector math and methods to normalize the movement vector in a better way. Precision!

- Enemies still jogging in place in this build, but you can zap them by clicking at them within 10 units distance to deliver a blow to them. This force vector is now calculated correctly and can serve in melee later.

- Begun building the valley's actual weather ambience piece by piece by piece. Debug overlay shows current weather and time. Reduced weathers from 27 defaults to 6 or 7 customs and altered appearances and weather chains. Changed galaxy color to have ominous green and teal present. More weather will come.

The valley currently will rain a lot for now. Let's see at least if the skies look appropriate for the valley.
