CVar shadowLOD

This variable controls shadows. This cvar defaults to 1.
* 0 - Turns off all shadows, including the character-only 'blob' type shadow. 
* 1 - Turns on shadows.
This cvar only works if extShadowQuality is set to 0.
To turn off all shadows:
 /console shadowlod 0
Note: As of 4.0.3a, this CVar still seems to exist technically in the console, but calls to GetCVar with this CVar return an error that the CVar is not found.
