Compiling Panda 1.90 Maya 2016 support files

For the record, while the devkit contains the header files, the .lib files that are also needed for building are not in there. I found I still had to install the Maya 2016 trial edition in order to get those so that I could build maya2egg2016.

For anyone looking for a development build with Maya 2016 plug-ins:
