Improve third-person mode usability

[Calinou]

• Don't clamp and divide pitch angle. This was vanilla Quake 3 behavior that other games rarely ever replicate.
• Draw crosshair while in third person mode.

This makes third-person mode much closer to games like Xonotic in terms of implementation.

If we want to improve usability further (so you have more chances to actually see what you're aiming at when aiming straight ahead), we can also increase the vertical offset which is defined here:

worldofpadman/code/cgame/cg_view.c

Line 249 in 72de7ef

view[2] += 8;

and here:

worldofpadman/code/cgame/cg_view.c

Line 277 in 72de7ef

view[2] += 8;

I use a value of 16 in Xonotic and it works quite well, although games like Serious Sam are closer to something between 24 and 32.

• This closes 3D Crosshair for 3rd-Person mode #9.

Thanks a lot for the merge request - unfortunately it doesn't work for me. I don't see a crosshair in 3rd person mode. And it's also kind of incomplete. The crosshair names should be shown, too - and we should also distinguish between death and normal game play. Because seeing the crosshair while being dead is not what we want here.

See e.g. CG_DrawCrosshairNames
