Made a CVAR for setting maximum horizontal speed when bunny hop prevention is enabled.
Made a CVAR for switching between reset modes when maximum speed is reached. Either full reset, or setting to max speed allowed.
Fixed error getting default classes on early player connect (bots, source tv, etc.).
Fixed jump boost not resetting height velocity. Changed to add to velocity. Jump from boost platform still doesn't work because the velocity is set too early.
Added check for reserved class names when validating.
Updated class default attributes and jump limits.
