SPB Warp

[Open Assets] SPB Warp v6

Changed cvar from spbwarp to spbwarptoggle so the game doesn't immediately crash when loaded with hostmod v18.

Change P_aproxdistance to FixedHypot so now there should only be 1 error message in console when the SPB is first thrown.

Added a bunch of new local variables so error messages aren't constantly generated in replays.
