Mob stepping sounds are inconsistently subtitled

Many mobs have different sound files and sound events for producing step sounds. However, the subtitling of these sounds is not consistent - some just display Footsteps, where others display the name of the mob followed by steps. This is not consistent.

This could be fixed by either repointing all of these into the one subtitle, or (preferably) by giving each of the mobs a unique step subtitle (perhaps somewhat personalized as well, e.g. Zombie shambles, Iron Golem stamps)
