##VERSIONS:
1.0.8	- compatible with factorio 0.14 (equipement grid change)
1.0.7	- removing on_player_left_game event that bugged in MP.
1.0.6	- rework of the whole mod :
		- tests if exoskeleton or other modifiers are present, so now computes the correct normal walking speed.
		- starts walking even slower than normal speed (customisable in config.lua)

		- before uninstall, to recover normal speed, use 
		   /c remote.call( "progrun", "off" )

		 /c remote.call( "progrun", "on" )
