[CGMZ] Footsteps - Version Alpha R4

Hi all, today this plugin was updated to version AlphaR4!

This version adds visual footsteps. You can now show a sprite when the player takes a footstep, which could be something like footprints through snow. This sprite can be customized with different graphics for each direction as well as how long it lasts before it fades. See below gif for how it can look:

This update comes with two fade modes for footprints, step and time. Time based fading will automatically fade after so many frames no matter how far away the player is, while step based fading will fade only after the player has taken a certain amount of steps. The fade is linearly interpolated from a start and end value which can be customized.
