Improved HSI

In preparation for Global, I propose that an improved HSI be implemented in IF. If you are unfamiliar with an HSI, here is a Wikipedia article explaining it:

As of right now, the sim has a HSI comprised of a CDI and heading indicator. The current CDI however, only has the options of tracking ILS localizers and GPS approach deviation. With global coming, navigation will have to be improved. The CDI should also be able to track VOR courses (available in the approach list to the right of the instrument) and GPS course deviation. This would also be good for the GA aircraft that won’t have LNAV and the handflying a length route can be accomplished without use of a GPS.
