Text-only routes in shield generator

[Jim]

I'm going through to update more systems with text only route names to display with green or brown squares, like we do for systems like usanp and usasf.  I think I can pretty easily add more colors.  Let me know.  So far, I've added (on the devel server only) green plain text for swemot.  You can put your requests/suggestions here.

usanyp should probably render the same way usasf does.
