Unity launching!

globals.cpp
+ constants for executable path and installations paths

interface_derived.hpp
+ OnOpenProject, OpenProject function declaration

interface_derived.cpp
+ event table for OnOpenProject
+ OpenProject now launches Unity. If it cannot find the unity version, it will alert the user.
~ fixed bug where substring length to get editor version was wrong
~ AddProject now inserts at beginning to match UI
