-    modifies per-player walking speed, jump height, and gravity.
-    Values default to 1 and act as offsets to the physics settings 
-    in minetest.conf. nil will keep the current setting.
-    sneak and sneak_glitch are booleans, default is true

 - hud_add(hud definition): add a HUD element described by HUD def, returns ID number on success
 - hud_remove(id): remove the HUD element of the specified id
 - hud_change(id, stat, value): change a value of a previously added HUD element
