Fix RPC accuracy

A crude fix for #1934 (closed)

The accuracy is still weird - if you make a direct hit and then one complete miss you'd expect 50% total acc but you get a lot more because the direct hit counts for 500 dmg and the miss for only 150 because explosions only do 150. I think some day we need to discuss how accuracy should behave and fix it across all weapons because this isn't the only inconsistency (RL with 150 or 200 damage counts as 98% on direct hit). I just wanna fix the obvious brokenness here.

Somehow i coldn't resist and also fix the perverted usage of space in function calls.
