alias mp_44 -> stg_44

aliasing mp_44 -> stg_44

reason: The latter term is the official designation of the rifle when it entered service, the former is name of the rifle during production/testing. The importance is that they are used often mixed up and used interchangeably, but only the latter is truly correct.

Whoops, can you change the alias to stg44
