Try to fix gun fov calculations in the softrenderer.

Browse source 
Until now the softrenderer calculated the fov relative to a hard coded
aspect of 4/3. That's wrong, because we're supporting arbitrary aspects
and we aren't calculating a fov but just a scaling factor to the global
fov which takes the aspect into the account.

Fix this by not taking any aspect calculations into account. BUT: While
this renders the gun with a correct perspective it's positioned much
nearer to the camera / player then in the GL renderers. The GL renderers
work around that problem by enforcing a minimal Z distance of 4 units,
which can't do because we're just calculating a scaling factor...
