New builds 2019-05-03

The biggest change in the new builds is that gravity has been lowered from 1.5 times earth gravity to earth gravity. The physics and animations have been tweaked in small ways in a few other places. Most changes are just whatever I felt was necessary to adjust for the changed gravity and smooth out the overall look. There are also some minor bug fixes to interacting with moving platforms and an issue with button icon colors in one very specific situation.
