*	Footsteps without view bobbing (#5645)	Louis Pearson	2017-04-25
| | | | | | | | | | | |	* Remove redundant view_bobbing setting Also fixes bug where disabling view_bobbing disables footstep sounds. * Removes redundant view_bobbing setting Setting view_bobbing amount to 0 is now the only way to turn view_bobbing on and off. Also fixed a bug where footstep sounds would not play when view_bobbing was disabled.
