script_nav_blocker

This entity is not in the FGD by default.
It should not be put directly in a map because func_nav_blocker already exists as a more accessible option.

script_nav_blocker is a point entity available in Left 4 Dead 2. Its a func_nav_blocker, readjusted for vscripts by being stripped of any unnecessary brush data. Other than that, what applies to func_nav_blocker is applicable to script_nav_blocker. Since its a brush entity technically, using the keyvaluesminsandmaxsstill works.

When compiling Entity Groups, func_nav_blocker entities are converted to script_nav_blocker.
