Started working on a Makefile to get PDFHummus to compile

under the minGW build environment.

+Today - we compiled all the .cpp files into object files. 
+The PDFHummus codebase did not have a build for anything other than
+MSVC. Tried to compile PDFWriter.cpp, but there were a huge amount of missing
+dependencies (both in source type declarations & missing include files).
+
+Previously, these were handled in the build tool, so we had to create a new build tool
+that also handled these problems. We found that nearly all (127) out of 152 source files,
+could be compiled without any dependency problems but that left 25 files to hunt down.
+Each of the files was put into a Makefile along with special compile flags to get them to 
+compile successfully. 
+At this point freetype2 has been compiled, but the other external libraries(e.g. libpng, zlib, libjpg, tiff, etc) need to be compiled so that we can link together an executable.
