Clinched Routes Highway Shields

Batch 8 is on tmstage for testing.

There was a bad line in the latest update to shieldgen.php.  Fixed in https://github.com/TravelMapping/Web/commit/1e154f78821510508e96b2f2913ab6b949cf5216 and now on tmstage for testing.

I guess Notepad decided to throw in some unfriendly quotation marks. Thanks for fixing it.

 - grca: Added code and missing template for 3 digit routes.

Everything else from Batch 8 looks good.

Looking at usasf, which has seen a lot of work lately, I wonder what's the ultimate plan for routes without a unique shield. Will the All American Freeway always be represented by a big green sign with "All Ame Fwy" on it, or will it and others like it eventually have their names spelled out (at least the ones with official, signed names)? Same for cansf and usanp, and probably others I can't think of right now.
