Clean up cruft and obsolete windows files

Added more visualstudio cruft to the .gitignore
Removed suo and vcxproj.user files, shouldn't be in repos
dsp and dsw files were from vc++ circa 1998
original sln and vcproj were from vs circa 2005
dev file was from an out of date version of Dev-C++
VC9.vcproj wasn't being used, other than conversion to vcxproj

moved sdl_winmain to windows folder, which was renamed win32,
and removed windows specific files from macosx project, all
to mimic what's already being done in /macosx (i.e. should
be for os specific files, not just ide-specific projects)
Remove empty and unused file
Remove dreamcast changelog and makefile
Remove Windows CE support (dreamcast vestige?)
Fix FizzleFade effect

The CRT hack caused the FizzleFade effect to be skipped, thanks
to that function writing directly to the screen surface (as opposed
to screenBuffer, which is what crt.cpp expects things to be written
to)
