Altered racesprite punch sounds and altered paths.xml accordingly.

Created by: Ledmitz

punch.ogg exists already for upmarmu, but this sound was intended to replace the original unarmed hit. I prefer to have upmarmu and a regular punch be indistinguishable. the branch magic_sfx_n_particles contains the upmarmu fix to remove the gloves, but travis.ci probably won't allow it? Unexpected sound errors, when no sprite tag is found.
