Worked on First Person View

Info:

Worked on the first person view and the HUD. The grenades are always displayed, the ammunition is visible when a weapon is drawn and will disappear if the weapon is placed in the holster.

The same applies to the heahlbar, except that it is displayed if the player loses some health and disappears if the player is at full health. Walking, running etc. now works in first person and feels kinda good 👍🏻
