NepDisk df581ae69f Remove dead renderer code 
based on 0eeacaf51e

remove
- broken viewborder code (if we really want it back for some reason, we should rather port RR´s fixed version of it)
- remove console clipping code for software (this was broken eiherway)
- remove hud message clearing stuff
- remove renderscreen and linesize variables (they just pointed to vid.screen and vid.widht)
