* Don't expose header windows.h in catch_all.hpp * Fix generateAmalgamatedFiles.py
This commits also adds a script that does the amalgamation of headers and .cpp files into the distributable version, removes the old `generateSingleHeader` script, and also adds a very simple compilation test for the amalgamated distribution.
