v0.8.72 changes — Kill the Man in the House Steam update #2918719

Added a slide because all FPS games on Steam are contractually obligated to eventually add a slide and air dash Reduced damage explosive barrels deal to the player Added some juice to the player health bar while taking damage Updated our level design CSG tool to the latest version which cuts down on "flickering" edges seen in the Terrific Tutorial level. Also fixed a floating point precision bug which fixes an issue we had on an unreleased level Added footstep sounds when the player turns in place Small fix for barrel kick direction to make aiming them easier
