Space Ninja Spawn and Stealth Glove Fix
Major Ninja Patch

Re-implemented some things that were removed a while back by somone who
had NO idea which way to hold a keyboard. (He made Phase Shift costless
by mistake, broke Adrenaline, made EStars cost your entire battery,
etc...). Fixed Ninja objective generation (It should actually happen
now!). As well as removed my implementation of the Kamikaze mode, as I
found there was a better one already implemented. Lastly I fixed the
NinjaHud so Vampires and their Thralls now show up properly on his HUD.
Totally worth my Christmas Eve.
