Fixed an issue with auto whitelist + admin function

Updated GetAdminsOnline with the new highest admin level. This fixes a
problem with the autowhitelist not turning the whitelist off when a
level 5 joins the server.
Tweaked spawn rates, added bike collisions

Bikes now have full height collisions to stop abusing the lack of a
character collision mesh to get into small holes.

Also renamed Taser to its correct name.

Also hotfixed a rare error for weapons.
