Remove some unused variables and options.inc which uFloat doesn't use, probably should never use, and was getting in the way of my testcase - but most importantly, remove the inline on hwSqrt which was causing very bad math on my compiler/machine. We may have to remove more inlining. A pity.

Don't test for hasGone in unapproved places. Now any possibility of desync on player quit is ruled out. Not tested at all.
