T4 ApiController Generator

This T4 assumes your DbContext is called ApplicationDbContext in a file called ApplicationDbContext.cs and does not account for whatever custom namespaces need to be imported for this file for your use. It is set up for DI, but lacks consumption of an IRepository pattern or anything similar. It also expects to be in a directory below the EnvDteHelper.ttinclude.
