Fixed Bug #7786

@speed no longer screws up on map change, modified @speed feedback so its clear whether the permanent speed flag is gone, enhanced @speed by making it capable of bypassing battle_config.max_walk_speed, made status_calc_speed rely on MIN_WALK_SPEED instead of the hardcoded 0, modified MIN_WALK_SPEED from 0 to 20 (it 1) wasnt being respected and 2) less than 20 clips).
@speed is now capable of moving the character faster, prior to this commit @speed 0 was equivalent to @speed 50 of this new version, @speed 20 for example is now the new maximum (and moves much faster).
