IupGui

I have chose Iup to be the `Official` gui library for ++coffee because it is easy to use and it is fast. The documentation is great. Despite being written for c/c++ and lua, I find it easily to understand the material. The only problem is that the Iup library's .dll and .lib or .o files fail to link well with the system. I'm using mingw64 on Windows 10. Simple gui components like buttons, sliders, windows, etc, work well and they link successfully and provide an exe output that runs as it is expected, but components like scintilla and iupweb are not functioning well. If linkage succeeds then the final executable will error out with `__g_personality0` missing or some function that looks like that. Have to fix this as soon as possible.
