I-80/I-580 Interchange in Reno

Fix for infamous at-grade intersection on I-80 in Reno. This mod replaces intersection entirely with 'cloverleaf' interchange serving I-80 and I-580/US-395.

v1.0b - Initial beta release, completed and tested on current public beta v1.2.0.2s but should work fine on stable 1.1
This version is still missing proper navigation signs, but this should not be a problem if you rely on in-game GPS instead of signs 

Thank you for trying. Please report any bugs and post suggestions here.
