[glass] Add glass: an application for display of robot data

This reuses many pieces of the current simulation GUI. The common pieces have been refactored into the libglass library. The libglass library is designed to be usable for other standalone data visualization applications (e.g. viewing data logs). The name "glass" comes from "glass cockpit", as the application features several multi-function displays that can be adjusted to display robot information as needed.
